Excellent question and good ref with Coase! We should all be perpetual skeptics, especially when we see so many similar opinions. In the crypto community you see an overwhelming bias towards decentralization, but we surely lose some of the benefits of centralization in doing so. Realistically, there's likely some time-varying equilibrium that's different for every business model, or industry.
Centralization could foster quicker decision-making since there are fewer people making decisions; consensus has costs in that it slows things down and convincing a group of people creates an additional hurdle. Sometimes the hurdle is good in providing checks and balances, but sometimes a single decision-making ends up doing the right thing.
