My point was not that mining pools completely do away with decentralization, just that contrary to your comment, additional network computing power does not necessarily contribute to that decentralization. It can in fact push it in the opposite direction. And the reason for that is mining pools. If it wasn't for mining pools, your statement would always be true.

There is a lot about this topic in the new, free book from Princeton authors titled "Bitcoin and Cryptocurrency Technologies" (a great read)[1]. There is much research being done on the front of finding the best way to eliminate mining pools or at least stop them from potentially centralizing consensus to just a handful of people.
