Imo, it's anything but totalitarian if it's a mix of voluntaryism in part of a gig / sharing-economy as a precursor before the shift. Armchair theorising is saying that abundance will flip the concept of money on its head. And yes it's quite like high-tech communism, and IMO perhaps part of decentralisation is the ability can accommodate many different systems with people participating freely without the capacity for any of these to be state-enforced by coercion. Would be interesting to see how their ideas may change for the better after getting some crypto enlightenment :)
