Hah "military cult empire" - that's a great name for the people/parties you're referring to.

The UK's labour party did all of that reforming in the mid nineties though, but I see what you're trying to get at with the coup's and neoliberal economic movements.

I'd really like to see what you described (the definition you gave for actually being "left") - in action. Unfortunately, democracies are inherently not very secure (tech may be able to solve some of this), because of other countries and bad actors. Open borders would make this even harder.

Would there even be a government in this situation? Or would this be more akin to a socialist technocracy?

Do you have any examples of any that have done it yet? Without centralizing any sort of power?
