If by "centralization" you mean giving more power to central entities that can intervene to fight local abuses and coordinate policies, I don't see a path were we can do without it.

We're in this situation in no small part because big enough companies can just buy their way when facing local entities, and the only recourse that is working is to ask a higher up regulator to intervene. Weakening the regulation entities makes it basically impossible to have anything done.
