So the dollar is the best of the worst..
That is an unintelligent statement.
To say something is the best of the worst, implies there is something better.
"Worse" implies a comparison against a better choice.
Unless you can identify this "better" currency that exists today, your statement makes no logical sense.
What I assume you meant to say was, "despite it's imperfections, there simply is no existing, viable option that is better or else it would already be in use." Which is what Ziehan was trying to explain to your type.
Nothing ever created my men will be perfect. Our currency only has to be a little better than the next best choice for it to be the logical choice for rational actors to choose in their own economic self-interest. Unless you think North Vietnam was using the US dollar for trade during the height of the Vietnam War because they liked us.
Everything else you say is just anti-American fueled, Q-Anon fever-dream, internet conspiracy prattle.
