This is too black and white what you are describing. Reality only knows shades of gray and every club, famliy, corporation and whatever reocuring social or economic gathering must have rules that are based on "force & coercion" and I would also add some sort of hierarchy.
A society without rules (stable or changing) is not capable of providing an environment, that suits its members in a way that they stay, because the price of instability (=expectational risk) usually is higher than some sort of submission (=expectational stability). Those rules can be given implicitly (usually family and friends) or explicitly (when it's about an utility) and why would that not include taxes (or something that has a different name but works the same way )?
For most of human history, these monopolistic centers did not exist,
I would also strongly disagree that history didn't know centers. There are so many, I won't make a list here. I see two difference between history and today. 1) We are many more, which means, we meet more often and clash more often, resources are scarce and 2) Our ways are much shorter and communication is crazy. Today we (=3-4 bn people!) can do on one day what people until 150 years ago did in their entire life span.
Both increases the systemic stress and my impression is that no-one really understands things anymore because they are so interconnected with a density that is ~1000 times as high as throughout history.
Decentralization is a smart move in such a regime, but not everyone is smart and you can gain a lot with the opposite. This again means, it won't be allowed, you just can't abolish sociopaths.
Well there's your problem, you're looking at the monopoly game,
Monopolies cannot be dismantled as well. Or should we try with Saudi oil? Siberia? How do we take that, how do we redistribute it and who will be in charge? You? Me? Jews? The collective?
"Politics" is, by its very nature, simply the doings of a small group who want to control others.
Yes, and you are enabling them.
Politics can also not be abolished. If politics wasn't needed and the market could fix all problems, no-one would have invented politics.
