I believe that the purpose of making the crypto decentralized is for security and to prevent one entity from taking it over. It will continue to exist even if one server or miner fails. The privacy and security provided in a decentralized network is what is needed.
Centralized would be nice only if we could trust that nobody would steal our information and our money. Unfortunately, that doesn't occur and the top one percent has all of the money in the centralized world. Nobody else can get any. It is easy for government and banks to grab what they want in the Centralized world. Do note that they can take what money they want when a collapse occurs. This is unfortunate that the people have to pay for failing institutions when the CEO's seem to walk away with millions.
I don't think EOS has problems and I think the group working on it is great.
