The amount currency "required" by an economy correlates to the size of the economy. The available energy commodities are not guaranteed to track the size of an economy. That's why we see fluctuations in the cost of energy. > A major issue is that we don't have anything that's usefully dense in energy content to use as money. I don't really understand this comment. If you're going to design a commodity backed currency, the energy density of the commodity is irrelevant. You don't have to swap uranium bars at the store in order to use an energy commodity as currency. You issue contracts representing your ownership of a specific amount of the commodity in a warehouse somewhere. Sound familiar? Commodity backed currency is not new. Swapping out the commodity just ties you to another system of supply & demand.
