I think you're making it smaller than it really is. At this point, it's part of a world religion A LOT of people live by, it's taught in schools and universities, it's made premise for a lot of fake science, etc. Predicted precisely by Guy Debord, 50y ago - but you won't see it being studied in universities because it hurts how they earn their bread :/
I really don't know. As mentioned I just see it from the outside. Our schools don't make America today a example for a great free market, the opposite might even be true. In fact the US is sometimes portrait as a danger to our 'free' market.
The fact that there is even the idea of a global reserve currency shows that the free market isn't as prevalent as people think. In principle people should be free to pick whatever currencies they want to conduct trade with.
