Let us first ask ourselves the question: Can money be organized under the freedom principle? Can we have a free market in money as well as in other goods and services? What would be the shape of such a market? And what are the effects of various governmental controls? If we favor the free market in other directions, if we wish to eliminate government invasion of person and property, we have no more important task than to explore the ways and means of a free market in money.

From Aristotle to Marx, men have mistakenly believed that an exchange records some sort of equality of value — that if one barrel of fish is exchanged for ten logs, there is some sort of underlying equality between them. Actually, the exchange was made only because each party valued the two products in different order.

A most important truth about money now emerges from our discussion: money is a commodity. Learning this simple lesson is one of the world's most important tasks. So often have people talked about money as something much more or less than this. Money is not an abstract unit of account, divorceable from a concrete good; it is not a useless token only good for exchanging; it is not a "claim on society"; it is not a guarantee of a fixed price level. It is simply a commodity. It differs from other commodities in being demanded mainly as a medium of exchange. But aside from this, it is a commodity — and, like all commodities, it has an existing stock, it faces demands by people to buy and hold it, etc. Like all commodities, its "price" — in terms of other goods — is determined by the interaction of its total supply, or stock, and the total demand by people to buy and hold it.

The establishment of money conveys another great benefit. Since all exchanges are made in money, all the exchange-ratios are expressed in money, and so people can now compare the market worth of each good to that of every other good. If a TV set exchanges for three ounces of gold, and an automobile exchanges for sixty ounces of gold, then everyone can see that one automobile is "worth" twenty TV sets on the market. These exchange-ratios are prices, and the money-commodity serves as a common denominator for all prices. Only the establishment of money-prices on the market allows the development of a civilized economy, for only they permit businessmen to calculate economically. Businessmen can now judge how well they are satisfying consumer demands by seeing how the selling-prices of their products compare with the prices they have to pay productive factors

Many textbooks say that money has several functions: a medium of exchange, unit of account, or "measure of values," a "store of value," etc. But it should be clear that all of these functions are simply corollaries of the one great function: the medium of exchange. Because gold is a general medium, it is most marketable, it can be stored to serve as a medium in the future as well as the present, and all prices are expressed in its terms.2 Because gold is a commodity medium for all exchanges, it can serve as a unit of account for present, and expected future, prices. It is important to realize that money cannot be an abstract unit of account or claim, except insofar as it serves as a medium of exchange.

sovereignty rests, not in government, but in the people.

Opponents of private coinage charge that fraud would run rampant. Yet, these same opponents would trust government to provide the coinage. But if government is to be trusted at all, then surely, with private coinage, government could at least be trusted to prevent or punish fraud.

Private minters can guarantee a coin at least as well as a government mint. Abraded bits of metal would not be accepted as coin. People would use the coins of those minters with the best reputation for good quality of product. We have seen that this is precisely how the "dollar" became prominent — as a competitive silver coin.

Champions of the government's coinage monopoly have claimed that money is different from all other commodities, because "Gresham's Law" proves that "bad money drives out good" from circulation. Hence, the free market cannot be trusted to serve the public in supplying good money. But this formulation rests on a misinterpretation of Gresham's famous law. The law really says that "money overvalued artificially by government will drive out of circulation artificially undervalued money."

Despite never-ending harassment by governments, making conditions highly precarious, private coins have flourished many times in history. True to the virtual law that all innovations come from free individuals and not the state, the first coins were minted by private individuals and goldsmiths. In fact, when the government first began to monopolize the coinage, the royal coins bore the guarantees of private bankers, whom the public trusted far more, apparently, than they did the government. Privately minted gold coins circulated in California as late as 1848.

What "should" the supply of money be? All sorts of criteria have been put forward: that money should move in accordance with population, with the "volume of trade," with the "amounts of goods produced," so as to keep the "price level" constant, etc. Few indeed have suggested leaving the decision to the market. But money differs from other commodities in one essential fact. And grasping this difference furnishes a key to understanding monetary matters. When the supply of any other good increases, this increase confers a social benefit; it is a matter for general rejoicing. More consumer goods mean a higher standard of living for the public; more capital goods mean sustained and increased living standards in the future. The discovery of new, fertile land or natural resources also promises to add to living standards, present and future. But what about money? Does an addition to the money supply also benefit the public at large? Consumer goods are used up by consumers; capital goods and natural resources are used up in the process of producing consumer goods. But money is not used up; its function is to act as a medium of exchanges — to enable goods and services to travel more expeditiously from one person to another. These exchanges are all made in terms of money prices. Thus, if a television set exchanges for three gold ounces, we say that the "price" of the television set is three ounces. At any one time, all goods in the economy will exchange at certain gold-ratios or prices. As we have said, money, or gold, is the common denominator of all prices. But what of money itself? Does it have a "price"? Since a price is simply an exchange-ratio, it clearly does. But, in this case, the "price of money" is an array of the infinite number of exchange-ratios for all the various goods on the market.

What makes us rich is an abundance of goods, and what limits that abundance is a scarcity of resources: namely land, labor, and capital. Multiplying coin will not whisk these resources into being. We may feel twice as rich for the moment, but clearly all we are doing is diluting the money supply. As the public rushes out to spend its new-found wealth, prices will, very roughly, double — or at least rise until the demand is satisfied, and money no longer bids against itself for the existing goods.

while an increase in the money supply, like an increase in the supply of any good, lowers its price, the change does not — unlike other goods — confer a social benefit. The public at large is not made richer. Whereas new consumer or capital goods add to standards of living, new money only raises prices — i.e., dilutes its own purchasing power. The reason for this puzzle is that money is only useful for its exchange value. Other goods have various "real" utilities, so that an increase in their supply satisfies more consumer wants. Money has only utility for prospective exchange; its utility lies in its exchange value, or "purchasing power." Our law — that an increase in money does not confer a social benefit — stems from its unique use as a medium of exchange.

An increase in the money supply, then, only dilutes the effectiveness of each gold ounce; on the other hand, a fall in the supply of money raises the power of each gold ounce to do its work. We come to the startling truth that it doesn't matter what the supply of money is. Any supply will do as well as any other supply. The free market will simply adjust by changing the purchasing power, or effectiveness of the gold-unit. There is no need to tamper with the market in order to alter the money supply that it determines.

Economists err if they believe something is wrong when money is not in constant, active "circulation." Money is only useful for exchange value, true, but it is not only useful at the actual moment of exchange. This truth has been often overlooked. Money is just as useful when lying "idle" in somebody's cash balance, even in a miser's "hoard."11 For that money is being held now in wait for possible future exchange — it supplies to its owner, right now, the usefulness of permitting exchanges at any time — present or future — the owner might desire.

Is hoarding really a menace? In the first place, what has simply happened is an increased demand for money on the part of the miser. As a result, prices of goods fall, and the purchasing power of the gold-ounce rises. There has been no loss to society, which simply carries on with a lower active supply of more "powerful" gold ounces. Even in the worst possible view of the matter, then, nothing has gone wrong, and monetary freedom creates no difficulties. But there is more to the problem than that. For it is by no means irrational for people to desire more or less money in their cash balances.

It is misleading, furthermore, to say that money "circulates." Like all metaphors taken from the physical sciences, it connotes some sort of mechanical process, independent of human will, which moves at a certain speed of flow, or "velocity." Actually, money does not "circulate"; it is, from time, to time, transferred from one person's cash balance to another's. The existence of money, once again, depends upon people's willingness to hold cash balances.

Let us assume the supply remains constant, say at 3,000 tons. Now, suppose, for whatever reason — perhaps growing apprehension — people's demand for cash balances increases. Surely, it is a positive social benefit to satisfy this demand. But how can it be satisfied when the total sum of cash must remain the same? Simply as follows: with people valuing cash balances more highly, the demand for money increases, and prices fall. As a result, the same total sum of cash balances now confers a higher "real" balance, i.e., it is higher in proportion to the prices of goods — to the work that money has to perform. In short, the effective cash balances of the public have increased. Conversely, a fall in the demand for cash will cause increased spending and higher prices. The public's desire for lower effective cash balances will be satisfied by the necessity for given total cash to perform more work.

People will almost always say, if asked, that they want as much money as they can get! But what they really want is not more units of money — more gold ounces or "dollars" — but more effective units, i.e., greater command of goods and services bought by money. We have seen that society cannot satisfy its demand for more money by increasing its supply — for an increased supply will simply dilute the effectiveness of each ounce, and the money will be no more really plentiful than before.

Money, in short, is not a "fixed yardstick." It is a commodity serving as a medium for exchanges. Flexibility in its value in response to consumer demands is just as important and just as beneficial as any other free pricing on the market.

Freedom of prices necessarily implies freedom of movement for the purchasing power of the money-unit; it would be impossible to use force and interfere with movements in the value of money without simultaneously crippling freedom of prices for all goods. The resulting free economy would not be chaotic. On the contrary, the economy would move swiftly and efficiently to supply the wants of consumers. The money market can also be free.

Private individuals who want to acquire more goods and services from others must produce and sell more of what others want. Governments need only find some method of expropriating more goods without the owner's consent.
