If each state bank is printing its own currency, there will need to be agreements between each state, to accept the others states currency, or, every time you travel, you will need to buy the currency of the state you are visiting - hopefully the exchange rate is not disproportionate, such as when you use an autobank in another state

Or you would need travelers checks, ie a currency symbol all states agree upon.

Traveling in America, would become like travelling in Europe was, before the Euro.

Its not hard, but does require a bit of planning before travel.

This is why they want to implement the state to state real ID. This is still total control in a different way over people. We need to push forward and go beyond to eliminate it all. Self govern.
