I agree and disagree. the major decisions need to be centralized because these guys are all have a pissing contest. The rest that is decentalize is working fine. Stop the pissing contests.
The model is proved to work perfectly since 8 years of track records. The decentralization is the key success of Bitcoin, if you want a CEO to manage it...you will transform it into a bank and nobody want that.
People will always disagree on some topics, but this is the human nature.
