one argument i've heard why sex work should be illegal is because it "traumatizes people."

no, it's not because that work is traumatizing, it's because you are monogamist and therefore you weren't suitable for the industry at the first place. you did things you didn't want to do. sex industry is solely just for polyamorous people.

not everyone is mentally capable to be traumatologist, but nobody is going to universally say "yeah don't be traumatologist. that profession will give you cptsd".
