Oh, wait! Won't it be better to keep 1MB blocksize and decentralized as much as possible, and in 2 years make a bitcoin sidechain with all your ideas implemented IF they actually proved correct?

Because Bitcoin Cash is the most centralized shitcoin in the entire crypto Universe. And Bitcoin Cash CEOs are proven crooks. And most importantly Bitcoin Cash doesn't offer any solution to the scaling problem.
