The very concept of a decentralized economy of the state is completely absurd, because not a single economy of the state can be decentralized by nature. The state economy has always developed according to plan, for the implementation of various projects and social programs, strict planning is necessary and such planning can only work in a centralized economy.
A certain degree of decentralization can only be at the local level; at the state level, there can be no decentralization.
I don`t agree with you! Planing, developing, implementation can work in every system, take a bitcoin for example for decentralized systems. Centralization just means that some people can make plans, but who guarantee you that their plan is a good plan?
In a country with centralized systems, like we have now all over the world, we have one huge problem. Head of that centralized system is a capitol city and people who live close, all others suffer cause of that (cities, villages, and everything else that is not close to that capitol city). Simple all the money goes there, and they decide about how to distribute it.
Decentralized system means one thing, all people have a voice! Not just handful of people who live in the capitol city. Think about it!
