Free banking=free people.
Money, of all types, is too important to be in the hands of government, and the elite.
The world trades everything. There are near two hundred different government moneys. No problem.
There is no reason there couldn’t be two hundred, or more, or less different money in the US.
How many different credit cards, different debit cards, store cards, bank cards are there? And, they work and are accepted. So too with private bank money, like we used to have in this country, before the Fed.
The only thing is big government Democrats, Socialists, Mercantilists, Republicans want a central bank, with federal power OVER us. Not US over them, as is the case now.
I am old. I remember having all silver coins and you could trade you dollar bill at the bank for a silver dollar. The bill said silver certificate where it now says federal reserve note. Now you can get a silver dollar for 20 bucks if you can find one.
