That the discipline of physics doesn't study everything doesn't entail that everything isn't physics. The title of the OP doesn't refer to the discipline. As for your other points, I'm familiar with the debates on physicalism in their various forms. I just believe most of them are elaborate semantic games with very little actual content. That people will ask what it means for everything (or anything) to be physical is precisely my point — stating that "information is physics" is a vague and (in my view) probably empty/tautological statement if you don't explain what you mean by that more precisely.
