Exactly. Well ... no. People are called Baker because some ancestor was a baker. Then over time the link from the name to the occupation got lost. Just as we might have "derive[d] pronouns from that" but are currently on the same way as with "Baker" - removing the word from it's physical beginnings.

If it helps - at least one party - communication to use different/new pronouns, this is where language will go.
