An evil fate befall German efforts to defend the ideal of liberty in general and in the field of economics in particular, with the result that today … - Friedrich Hayek

If the world as a whole returned to the gold standard there would be such fluctuations in the value of gold that it would very soon prove impractical.
Today an international gold standard could only mean that a few countries would maintain a real gold standard. The other countries would hang on to the system through a gold exchange standard — where the currency isn't really redeemable in gold but the government attempts to keep a fixed rate between its currency and gold.

All the paradigms of culturally evolved institutions, morals, exchange, and money refer to such practices whose benefits transcend the individuals who practice them in the particular instances. The result is that whole groups may be helped by them to expand into what I shall call extended orders, through the effects of practices of which the individuals are not aware. Such practices can lead to the formation of orderly structures far exceeding the perception of those whose actions produce them. They make possible the adaptation of such actions to unknown circumstances and lead to the formation of an indefinitely expansible order which can develop only through group selection, that is, a selection of groups for common attributes possessed by them.

What I expect is that inflation will drive the Western countries into a planned economy via price controls. Nobody will dare to stop inflation because to discontinue inflation will inevitably cause extensive unemployment. So assuming inflation stops it will quickly be resumed. People will find they can't live with constantly rising prices and will try to control it by price controls and that of course is the end of the market system and the end of the free political order. So I think it will be via the attempt to regress the effects of a continued inflation that the free market and free institutions will disappear. It may still take ten years, but it doesn't matter much for me because in ten years I hope I shall be dead.
