states have proven time and time again how they manage to screw up money
i'm skeptical that any system where the state has control wouldn't be subverted like always
most economists or financiers would include "a store of value" in the definition of "money", but no fiat today is a store of value as its value is eroded by inflation
until that is addressed, money isn't money anymore
also, Pierre-Joseph Proudhon is a nutter
