No one had faith in the Zimbabwean economy hence hyperinflation when they printed money.
The world has faith in the US economy hence the US can do quantitative easing and the worst that happens is ~7% inflation (also caused by the worst supply chain problems in history, a global pandemic and a major European war).
Note that Bitcoin has lost more value than the US dollar.
How does that make any sense? It's up more than 26,000% against the US for ten years now. What time frame are you working with?
Since inflation has been an issue (since the OP raised hyperinflation as a risk).
That's a bold statement. I guess by "the world" you mean US, EU and Japan. That's not even half of "the world".
Different countries have their own currencies. In most of them, it's illegal to use another's country currency. So this statement doesn't make a lot of sense to me. Regarding most currencies being attached to the USD, it's an old tradition that a lot of entities are trying to get rid of. Some got democracy just for trying to get out of it (Libya comes to mind).

This is such a low-effort analysis of the geopolitics of the Arab Spring that it doesn't even make sense to argue.
