The standard money story inevitably goes something like this:
“In the beginning there was barter, with people trading chickens for corn. Then people invented money in order to deal with the inefficiency of this. They nominated a particular commodity to be a universal ‘store of value’ and means of exchange for transactions between all the other commodities. Precious metal coins satisfied the characteristics necessary for this, but at some point we started using paper money, which isn’t really a commodity but is still a store of value. And now we are moving to digital money, a world where money is ‘dematerialized,’ becoming mere bytes of information … ”
You should be intensely skeptical about all of this.
