Texas Notes would be accepted in Texas, and any other state that deems it acceptable. I don't see the problem if the "Texas Notes" quickly pushed out of the market; that's the point of competing currencies. The best currency is used. If there's an arbitrage opportunity by buying Texas Notes and selling gold backed dollars, then that too is not a bad thing. Are you saying they are mutually exclusive b/c eventually one currency will be settled upon i.e. mutually exclusive in practice over time, but not mutually exclusive per se?
Yes, I am saying they're not mutually exclusive per se, just practically impossible to maintain equally over time.
No, not forced. I meant Florida, the State will accept Swiss Francs in addition to dollars. So one would have a choice in which currency to pay their taxes, fees, etc.
I think the point of competting currencies is that eventually the best currency will be used.
at that point, there would either be no gold standard, or a gold standart would render competitions irrelevant.
