It is particularly odd that economists who profess to be champions of a free-market economy, should go to such twists and turns to avoid facing the plain fact: that gold, that scarce and valuable market-produced metal, has always been, and will continue to be, by far the best money for human society.
Gold was not selected arbitrarily by governments to be the monetary standard. Gold had developed for many centuries on the free market as the best money; as the commodity providing the most stable and desirable monetary medium.
I see a great future for gold and silver coins as the currency people may increasingly turn to when paper currencies begin to disintegrate.
If government manages to establish paper tickets or bank credit as money, as equivalent to gold grams or ounces, then the government, as dominant money-supplier, becomes free to create money costlessly and at will. As a result, this 'inflation' of the money supply destroys the value of the dollar or pound, drives up prices, cripples economic calculation, and hobbles and seriously damages the workings of the market economy.
I want to make it clear what I am not saying. I am not saying that fiat money, once established on the ruins of gold, cannot then continue indefinitely on its own.
