 This line might succeed as an objection against the claim that cases of self-location require us to modify our theory of propositions (as, for instance, Lewis suggests). Perhaps if we had a theory of propositions that successfully handled Frege puzzles, it would apply mutatis mutandis to these cases as well. (Though see Shaw 2019 for a denial of this concession.) But that is no argument against the existence of a distinctive category of self-locating beliefs.
