Well, the possibilities listed up-thread other than “you don’t exist” make the problem no longer exactly Newcomb’s problem, unless you two-box. So I like your favorite, although I’m probably thinking of a stricter version of “don’t exist” that makes it more nonsensical to talk about “what would you (who don’t exist) do?”
E.g. if carrots didn’t exist, what would the carrots that don’t exist taste like? :D
