There is 2 kind of centralization. One is based on excellence, like the best of the best climbs up in the hierarchy due to it's excellent qualities. In the free market this is voluntary, so the company that serves best their customers gains a natural monopoly or oligopoly with other good services.

And there is another way where they use the power of the State to force out competition through regulation, taxes, IP laws, and environmental regulations (which are not for the environment but for mega corporations fucking with the 3rd world).

The State does massively more harm to the economy than anything other imaginable. Since it is literally in the interest of the State for people to stay poor and dependent on it. The last thing they want is people to be independent and prosperous, then they won't need them anymore. If everyone is sovereign, then you don't need the king anymore.

Blockchain and internet based initiatives will form the framework of the new society, the State will go away in a few centuries, and we will have a free world.
