we don't need no monetary policy, just some oversight that the label does not lie, just like the govt does not sell food but makes sure the label on food packaging is correct!anyone could issue anything as a monetary unit, it is called private money or free coinage; banks, companies, individuals, everyone could create their own money and offer it to the public (this could be cryptocurrencies, foreign currencies, metals, grains or just plain fiat notes)
mines would offer metals, naturally, oil companies petroleum product covered notes, farmer might offer a currency backed by grains (like Germany did after WW1) et cetera. paradise. no more fiat slavery, no more cheating and no more big government.
governments only job would be oversight
e.g. if silver coins from Walmart say 1 oz, they must contain 1 oz
then the Fed would just be one out of hundreds of money issuers!!! HAHAHA just joking, nobody would use their junk bills if they had a choice
