Farma, say we take the roughly 50 commodities (including gold), and weight them according to demand. We end up with a commodity index (they already exist) This index is going to move up and down, like all things. All economies then uses units of the commodity index as a global currency. So, commodity based nations are not at a advantage. So I work and earn units. These are digitally exchangeable. The concept of national currencies disappears and we have a global currency. I turn up at your farmgate with a method to transfer my units to you. Is this simplistic? Of course, but there's a germ of a possibility there.
