So BitUsher also cedes the point that SegWit does nothing to ease centralization due to burden of larger blocks upon fully-validating nodes. Joining Lauda, exstasie, and forevernoob. Excellent. Who's next?

Removing the rules against actions that the network protocol expressly forbids against the will of an economically significant portion of users, and risking a persistent ledger split in the process is not a comparable thing. It's something that Bitcoin Core strongly believe it does not have the moral or technical authority to do, and attempting to do so would be a failure to uphold the principles of the system. It's not something to do lightly, and people who think that it's okay to change the system's rules out from under users who own coins in it are not people that I'd want to be taking advice from-- that kind of thinking is counter to the entire Bitcoin value proposition.

Finally--at some point the capacity increases from the above may not be enough.  Delivery on relay improvements, segwit fraud proofs, dynamic block size controls, and other advances in technology will reduce the risk and therefore controversy around moderate block size increase proposals (such as 2/4/8 rescaled to respect segwit's increase).
