-But "plan to get hair surgery"? "Would get hair surgery if it were safer but for now are afraid to do so"? In what sense do these cases present a challenge to the discrete system and therefore call for complication and nuance? There's nothing ambiguous about these cases: if you haven't, in fact, changed your hair color, then your hair is, in fact, its original color. The decision to get hair surgery does not _propagate backwards in time_. The decision to get hair surgery cannot be _imported from a counterfactual universe in which it is safer_. People who, today, do not have the hair color that they would prefer are, today, going to have to deal with that fact _as a fact_.

+[^pronoun-roles]: If the problem is with the pronoun implying stereotypes and social roles in the language as spoken, such that another pronoun should be considered more correct despite the lack of corresponding hair color, you should be making that case on the empirical merits, not appealing to hypothetical surgeries.
