I don't see how. Please explain how consensus around increasing the blocksize is ever going to happen? Because again, it will only lead to 2 things:

1) Bitcoin will continue with 1MB as there will still be people mining and transacting on it
2) There will be a 2MB or whatever blocksize hardfork, which companies and exchanges will claim it's Bitcoin, even if Core team agrees, it doesn't make it Bitcoin

So you will have the legacy chain existing and the new chain existing, and we already have this (Bcash).

The blocksize cannot be increased, it will always lead to a new altcoin, which some may call Bitcoin. Bitcoin is basically impossible to hardfork at this point (without again, ending up with 2 coins).
