Definitely a self consistent theory, I’ll give you that. I’m not sure nation state issued fiat lead to an economic miracle, but without that assumption the argument falls apart.

That said, the US has been fairly assassin-y when it comes to middle eastern countries selling oil for anything other than dollars, so we can’t dismiss the video’s claim out of hand.

I prefer to think about things as questions rather than conclusions. Why? Because my personal belief is irrelevant and not required. I chose to have no view on past events but rather wish to discuss how one evaluates claims about past events. And when decisions need to be made, one must dive deep and find answers to the questions revealing the past. But often decisions don’t need to be made.
