Many people—many economists—usually devoted to the free market stop short at money. Money, they insist, is different; it must be supplied by government and regulated by government. They never think of state control of money as interference in the free market; a free market in money is unthinkable to them. Governments must mint coins, issue paper, define “legal tender,” create central banks, pump money in and out, “stabilize the price level,” etc.
