I agree with you from a mathematical point of view. You have this "dead economy theory"[0]. I spent a lot of time trying to model this theory, enhance the theory (lot of good HN comments) and find a "middle ground" path. My saying is that you end-up on an optimization saddle point where it is really hard to not fall into concentration of power. I was able to get radical abundance only at the cost of pretty hard regulations.
