People constantly cry out for decentralization. In reality, however, most systems eventually end up centralized. Perhaps when people ask for decentralization, they are actually seeking a new center where they can become the new pioneers. It seems that when they feel they have no chance of winning under the existing rules, they use decentralization as a pretext to overturn the board.
Decentralized means no single center. Of course people want it because the single centralized management is insufficient for some reason or another.
There is no difference between what you say people cry for and what you say they actually want.
I think decentralization is the wrong answer for what people really need: portability.
I think some people are mentally ill, and think decentralization is a libertarian ideal where they can have all benefits of society, but they don't have to pay for the roads, the fire department, etc. That some how, those things will spontaneously appear because of <free market babble>.
Others recognize there's some kind of more comfortable middle ground where decentralization means the same as a town/city/state type of social good that is independent and capable of working without larger centralized structures. Having to work towards it, pay money into it, etc, are expected but because the work that goes into maintaining the infrastructure has a clear line of derivation (taxes clearly go to X, Y, Z) would be a benefit.
It's typically the first class tho that dominates all conversations regarding decentralization, and that class includes the Epstein billionaires who just dont want laws to apply anywhere they want to do unethical, immoral and whatever. eg, money is the only law.
