Build your “structure outside the political system” and wait until the first discussion where someone wants to impact someone else. Boom, it’s a political system again! Can’t have a few hundred million people without various governments forming, de facto or explicit. And frankly the idea of a society without any kind of regulatory bodies is a nightmare.
That’s a strange thing to fixate on considering it’s absolute nonsense. They work because they look cool as hell but nothing about them makes sense in a logistical way.
Why are the defense batteries manually aimed? Why are capital ships engaging from within visible range? Why do they only do the lightspeed-suicide maneuver one time when it’s clearly the perfect weapon in space? Why do they fly like they’re moving through air?
