This is not going to prove anything. People now see Bitcoin forks as a way to get "free money." As many have already stated, the more forks the better, more free money for me.
It's an interesting take, but you're forgetting one thing: Bitcoin Cash had replay protection, and Bitcoin Gold is supposed to have it once launched. BIP148 did not have replay protection, and as of now, neither will Segwit2x.
A hard fork with replay protection is literally free money, since using the legacy chain has no effect on the forked chain. Without replay protection, using money on one chain might mean losing it on the other. This is unprecedented so far. If the Segwit2x fork is as ugly as it could possibly be, many people will lose coins trying to get that "free money." Then, attitudes towards incompatible forks, network splits and replay protection will change.
