With all due respect, the analysis that this “proves” all of these things is quite a strong claim. It is, at least, equally as possible that BIP-110 was simply not a good enough of an idea for most of the network to want to adopt it. Just because BIP-110 didn’t pass, doesn’t mean that somehow that Bitcoin is too centralized. It could also just be a humility test that a better idea is needed. There are so many better ideas to solve these issues than BIP-110. Such as removing the witness discount.
