Yes, but I'm actually going somewhere with this: EY doesn't believe that "infinite sets exist" (loosely put). So I'm trying to deduce constraints on what "exist" can mean and still be coherent; at this point I don't think we can even claim that lavalamp's kangaroos "don't exist".
Has EY articulated a position on "infinite set atheism" outside of a few off-hand comments, that are possibly jokes? You might be preparing to rebut a position that he hasn't taken.
Well, I've seen him go into quite some detail in comment threads about uncountable ordinals; it looks to me very much as though there is a position there that he's taking (it's fairly clear that it's more than just a joke). OTOH, I haven't seen an article by him setting out his position in a rigorous or articulated fashion, though if there is one I'd like to know about it.
