This is very sound logic and would probably work but I think the biggest challenge and in turn the nearly impossible to pass hurdle is that this requires the whole world to act in unison and have a single system of money and distribution, which is impossible when we can’t agree on much pettier things such as the pronunciation of schedule or the spelling of color / colour.

I like how you talk about equal “ownership” of capital vs equal distribution of money because the latter causes bigger problems of lack of incentive and hence an inevitable breakdown of the globak system in practically no time.
