Good advice for you actually, since you don't know what you are speaking about. So just try to read what is written here, and if you don't understand what is written, or you have some problem with it, then just try to ask politely about it, so that I or others who are more informed that you can explain matters to you. Anyhow standard set theory "ZFC" is of course not limiting itself to the potential scenario, not even to the one I've presented here, that's why it accepts Impredicative definitions, as well as non well founded versions of it, the reason is that it doesn't have a problem with considering the possibility that all sets in the universe of discourse are GIVEN beforehand, and Godel's have stated that there is nothing wrong with this assumption, so there is no problem with considering that the set N is already Given, i.e. it is there beforehand with all its elements, i.e. N is a completed actual infinite set, in standard set theory understanding of N is not limited to the potential of becoming that I've presented here. However here I showed that even if we assume potential infinity in the sense I've presented, which is as I showed here the most faithful to that concept itself, then still Cantor's diagonal argument applies to it. All of what I'm saying here is that standard set theory as customarily understood doesn't not restrict itself to a potential infinity context, but even if so then if we faithfully represent that concept of potentiality then Cantor's argument can be still carried on.
