It is like playing the second-derivative game of the Fed today. It's a little like letting stockbrokers run your monetary policy. Three atoms of gold might buy 36 baud from and 100 baud from my neighbor. Across borders, I can only make meaningful promises for exchanging future capacity with my local neighbors. There is a single monstrous simultaneous equation being solved here.
Greenbacks have a brand-name premium.
Only the british pound and the deutchmark and perhaps the yen might make similar claims. What we need to do, what has not been done before in the history of central banking, is to privatize the branding of currencies and translate that prestige into profits. Suppose I buy two munchkins, and program them to trust each other. One is at my apartment, one is at the lab. Now, if Caltech installs a munchkin network along ring road, I have a problem.
