To a naive observer, money made out of precious metal was 'sound money' because the piece of precious metal was an 'intrinsically' valuable object, while paper money was 'bad money' because its value was only 'artificial'. But even the layman who holds this opinion accepts the money in the course of business transactions, not for the sake of its industrial use-value, but for the sake of its objective exchange-value, which depends largely upon its monetary employment. He values a gold coin not merely for the sake of its industrial use-value, say because of the possibility of using it as jewellery, but chiefly on account of its monetary utility. But, of course, to do something, and to render an account to oneself of what one does and why one does it, are quite different things.
~ Ludwig Von Mises
