What I had in mind is that if you drop the axiom of extent you can either conclude that there is no such list or that the anti-diagonal does not exist analogously to the conclusion that the set R = {x | ~(x in x} does not exist.
BTW, Cantor did not work in ZFC and the argument given by McCullough appeared to be on the intuitive level rather than in any particular formal theory.
I will grant you that Zermelo figured how to construct a system where the diagonal argument goes through and his system is probably consistent. It is a nonsense nevertheless. All the transfinite set theory is a completely superfluous metaphysics.
