I believe the most likely future is a complete bifurcation between the productive and unproductive... with each group passing different money. The unproductive will pass Federal slave tokens of some type and the productive will only accept and use a form of sound money: gold silver bitcoin. I'm seeing this in Argentina already with the farmers in the Pampas refusing to take pesos for their soybeans and having "terrorists" vandalize and destroy farmers stockpiles of soybeans they refuse to take to market at the current manipulated prices.
