If a nation can use another nations money that way, what stops all other nations to do it as well? It would be too much centralized in every single nation to be ruled by USA, sure venezuela is a small sample size and USA won't even care but if you for example make %50 of people in Europe to start using dollars instead of Euro, that would be a demise of all european union and all nations withing since USA would basically control them. So it doesn't look all that bothersome to people since its venezuela and they might actually take advantage of this situation yet I still think we should try to stop and eleminate this idea before it spreads to all other nations in trouble, that would make it very difficult to reverse.
