Nash's ideal money sounds super groovy man, but pegs won't work. If ya want to stop the politicians from spending, put forth a bill for a balanced budget but leave the price of the currency for the market to decide.
Right. I have a library full of Paul Einzig, for one, who was in his day considered the foremost commentator on currency matters. I don't recall a single mention in any of his books, including his well-regarded History of Foreign Exchange*, of energy. Not one. Can't imagine why. *[size=-2]I also did a search for the word "energy" on that review of it I linked to. No mention.[/size]
