You have attacked a commonly held myth: Bring back the gold standard like we had in the Good Old Days.
Money, in whatever form, is very abstract. As long as the illusion is maintained, it will work. Other than a few blips, it has worked out well.
I won’t claim to understand monetarist economics, but I still find it amazing that this sorcery has held together for decades. Maybe the wizards knows what they are doing; maybe the monetary system will crash. But going back to gold is no solution.
