Two things and two things would still be four things. The fact another thing would pop into existence is irrelevant. 2+2=4 .
You're equivocating.
As for the rest I've already dealt with it. Once again if you don't understand this:

THAT is the implicit truth of The Law of Identity and THEREFORE it's true in all hypothetical universes.
Then there's no hope for you.
All hypotheticals and all premises presuppose the law of identity I don't give a fuck what universe it is. The Law of Identity is more fundamental than that.
You can't even say "If there was another universe without the law of identity then there would be another universe without the law of identity" because you can't even have a tautology like that without first implying the law of identity. The sentence "if there was another universe without the law of identity then there would be another universe without the law identity" implies that "if"="if" "then="then" "another universe=another universe", etc, etc... and guess what that is? The law of identity. You're screwing yourself without realizing it. You can't even have a tautology, or a defintion, or a hypothetical, or a premise without implying the truth of the law of identity so you can't define a hypothetical universe without it even when you think you are.
