there have been lots of currencies issued by non state actors. esp in the 1900's - 1930's. anyone with gold in the US could make notes and issue them out. The assumption that any gov cant control it so it wont be allowed - that is a pretty sad and scary statement. that the gov and not the individual is in charge of their own money. this is the problem. that the gov - made, designed, enacted by the people, for the people - is actually working against the people.
whatever democratic, duly elected gov structures were initially created for - at least the developed ones - those ideals are long gone. as is the way of all things, democracies have a golden period. this is where the elected people work to increase the standard of living for all citizens. where education is cheap and citizens become healthier and wealthier over time. we are past that.
established democracies see professional politicians, elites, higher costs of living, widening wealth gap. the country becomes one where everyone is out for their slice. this takes a once in a lifetime leader to change. or a once in a lifetime change in something that removes the power from govs, elites and forces them to negotiate or at least offers an alternative to a citizen.
