Thanks for writing out your thoughts. This would have been easier to read with shorter paragraphs, but it's a good post nonetheless. I think the Bitcoin blocksize debate (stalemate) is just a symptom of dysfunctional governance. We are just starting to learn how important governance is to blockchains, and different solutions are being proposed.

Tezos is one interesting take on the problem, and there is an active planning going on in the ETC chain. And I guess everyone, especially Ethereum Foundation, learned a lot from the DAO situation and the resulting fork. These are just growing pains of the whole ecosystem, and good things will ultimately follow.
