Wut. I don't know of a single entity on earth, government or private, legal or illegal, that wouldn't accept US dollars in some form or other. I wouldn't say the same about Bitcoin, much less other forms of crypto.
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.
