Gold Socialism or Dollar Socialism
Mises demonstrated, as early as 1912, that no good can become a medium of exchange, much less a money, unless it has a previous non-monetary usefulness on the market. In short, money can only emerge as a commodity on the market, and cannot be imposed by the government, by social contract, or by various schemes of economists or other observers. Such plans have elsewhere been labeled correctly by Hayek himself as "constructivist." In short, media of exchange and therefore money can only arise "organically" out of market processes and cannot be imposed by outside schemers.
