It’s an unfortunate historical anomaly that people think about the paper in their wallets as money. The dollar is, technically, a currency. A currency is a government substitute for money. But gold is money.
Now, why do I say that?
Historically, many things have been used as money. Cattle have been used as money in many societies, including Roman society. That’s where we get the word “pecuniary” from: the Latin word for a single head of cattle is pecus. Salt has been used as money, also in ancient Rome, and that’s where the word “salary” comes from; the Latin for salt is sal (or salis). The North American Indians used seashells. Cigarettes were used during WWII. So, money is simply a medium of exchange and a store of value.
