Interesting notions, but the all powerful mainstream economists already treats money as exogenous and look where that got us. Also, how would any nation without sufficient military to back its super-fiat currency engage in trade? Or how would investment banking, which is really the corrupt core of our society, cope? You need to think a bit one how we get from here to there. Have you run any of these ideas by the folks who study monetary policy from a heterodox perspective.?
