Money in a Free Society
Rothbard begins by smashing the myth that money is created by the state. Instead, he explains that money originates from the free market to solve the limitations of barter. In a barter economy, you need a "double coincidence of wants"βif you have eggs and want shoes, you must find a shoemaker who wants eggs.
π Key Insight
Money is simply a commodity that is the most marketable. It is not an abstract unit of account ordained by government, but a tangible good chosen by the market.
Historically, gold and silver became money because they possess specific qualities: they are scarce, durable, divisible, portable, and uniform. When a society adopts a commodity as money, every price becomes expressed in terms of that commodity (e.g., "1 ounce of gold").
