Does it need to be centralized vs decentralized?

The human organism is (IMO) an awesome demonstration of both centralization and decentralization. As is the little blue speck we call our home biome.

What I might accept is that proponents of both arguments ("we need more centralization so we can provide a better service" vs "we need more decentralization so we have the freedom to evolve better services") ideally come to realize that there's a yen and a yang to the whole thing. That there's a lack of healthy balance/harmony between the two is a pretty easy argument to make now days.
