If it comes to armed conflict among the general population those fiat dollars vanish, past contracts are void.
I think you grossly overestimate the number of people who actually value the existence of Bezos and Musk types. Most among the right and left voters see them as lazy non-contributors, propped up by political corruption.
The right feels serving a king under a different name is wrong. The left finds it anti-scientific and conservative to preserve the rich given their wealth is heavily influenced by conservative politics. It’s a good thing for elites the right leaning voters are easily manipulated, since “both sides” voters polled actually want the same thing; the rich minority to be gutted and their power handed over to local communities.
This is what worries me. Once you can create your own army that doesn't sleep and doesn't question what you ask it to do. The ruling class will have no problem killing people in mass because who will stop them. In theory they wouldn't have to kill a lot of people to convince the majority of the population that its not worth fighting them. We're getting close to where we won't be able to turn back.
