It is not an economic rule that gold equals wealth. Gold's value is based on someone's willingness to buy it from you. In that sense, it's the same as fiat. Of course, you can't print it and blah blah blah, you've heard the rest. Regardless, ECONOMICALLY speaking, there's no magic law that says gold is money.
