1. I'm not really sure what you are asking. If this helps, what I want (and what I call a free market) is a situation where people are free to make their own decisions because the use of non-preventative force is barred. The government uses preventative force to prevent other people from using force. This is a "domestic" issue. It doesn't really have anything to do with international relations. 2 and 3. If you go back to my example, customers don't want Shitcoin in the first place, so realistically, they would never seek to obtain it. So it isn't really the case that customers are trying to get merchants to take their Shitcoin. There just isn't any point in using it at all. The reason "bad money drives out the good" in Gresham's law is because the government puts the bad money into the economy. Absent something like that, bad money just isn't wanted and nobody keeps it. If they get it they immediately convert it to a good currency, so if it pops into existence somehow, it immediately goes out of existence. Visa and Paypal and whatnot are not different currencies. They are different payment mechanisms. I agree with you that customers and merchants would likely want to use multiple of these, and that merchants would be driven to accept all the common payment mechanisms. This has been a worthwhile discussion and I'm sure we could keep going, but I really have to take a break from hacker news for a while. So let's call it a day.
