I mean centralization is fine, but there's no reason to use a blockchain if you are going to be centralized. Just use a central database with a few backups, it's more efficient. Centralized blockchains make no sense. The blockchain is a security mechanism that is fragile. If you break the mechanism, there's no real reason to use it. It's a hybrid that makes no sense. The worst of both worlds. Slow, Inefficient, and vulnerable to internal corruption.
