Money was a sign of real commodities, but credit was but the sign of a sign.
There was a natural limit to gold and silver, that is, money proper, but none to credit, and the result was that the volume of credit, that is, the promises of money, ceased to bear any ascertainable proportion to the money, still less to the commodities, actually in existence.
Under such a system, frequent and periodical crises were necessitated by a law as absolute as that which brings to the ground a structure overhanging its centre of gravity. It was one of your fictions that the government and the banks authorized by it alone issued money; but everybody who gave a dollar's credit issued money to that extent, which was as good as any to swell the circulation till the next crises.

I suppose some are just risk adverse. With proper risk management, credit can help achieve your goals faster. Of course, most of such tools aren't readily available to the retail investor or the ill informed.
