^^^This^^^ Is as concise and as best I can explain why The Law of Identity must hold in all hypothetical universes and you can't even have a premise or a hypothetical without it. The truth Law of Identity is already presupposed when hypotheticals and premsies are made (whatever hypotheticals and premises are made they are whatever they are and they mean whatever they mean. A=A ~ The Law of Identity. Without the truth of that presupposed you've failed to even make a premise or a hypothetical.). If anyone doesn't understand this then I don't see how I can possibly explain this any clearer. This is 100% correct.
