This doesn't scare me as much as it probably should. I think that if this happens, you'll only certain sectors use it. Most Americans will use it where they have to, but rely far more on barter ormperhaos an "undercurrency."
Yes, but anywhere you use it the government will have a record of it. And do you not think they'll want more control than that? So, the government will have to approve of your purchase for you to be able to use your money.
