[TODO: We want words that map onto the structure of things in the word: if everyone were a hermaphrodite]
In a world where sexual dimorphism didn't exist, where everyone was a hermaphrodite, then "gender" wouldn't exist, either.
In a world where we _actually had_ magical perfect sex-change technology of the kind described in "Changing Emotions", then people who wanted to change sex would do so, and everyone else would use the corresponding language (pronouns and more), _not_ as a courtesy, _not_ to maximize social welfare, but because it _straightforwardly described reality_.
