I think I had answered this one already and being burried deep already.

Anyway, the world without fiat in my opinion is a chaos. The world now is organized due to a system like fiat currency. It may not be perfect but at least it works. However, it creates division among others like the rich and less fortunate people. This becomes the unlikely result of the system. The communist had tried to avoid this one but even in the communist country there are still caste system where rich people are on top and some that are poor considered as slaves.
