Miners already have enough control with their hashrate. I prefer a plurality of influencing actors (miners, exchanges, developers, main whales, relevant individuals, users, etc) as a form of power decentralisation.

I do agree block size is not that much relevant (within some common sense boundaries). So that's why I am fine with a moderate (2x) blocksize increase.... delivered by CORE developers and in the safest possible way.

I am totally in disagreement with more power/control "flippening". Let's just have some respect to the "status quo" that have lead us to where we are right now and keep evolving slowly and without ridiculous experiments and power unbalances.
