This is an absolutely excelent thread, this brings it to the open, how much demage the ideology of a nation state has already caused, and this is not even a specifically American problem.
Unless you sell to the federal government, it is not a nation that is your customer, but a community. If you want to pay for labor and services, you don't buy that from a nation, you buy that from the communities that you operate in.
So, what good is your nation for you? To force you to use a "legal currency"? Luckily, in the USA the law allows everyone to invent his own currency if he can get enough others to use it with him. (One of the reasons I love the USA.)
But even with that, we all know those newspaper articles about how viciously the federal IRS clamps down on "bartell traders".
And then add that most of your taxbill is not even where you operate, it is to some remote federal account. And communities then go to beg for handouts from the federal monies. This system is currently your disgrace, it would only work in Europe, where communities are true enemies of each other, not only co-competitors. In the Unites States, you would be MUCH better off to see yourself as a person with your local identity, instead of making a whore out of yourself for national trickery. Remember the Founding Fathers and what they wrote about.
