I think people are too quick to dismiss this point of view. I have very little patience for your recent tendency to frame arguments as condemnations of individualism vs. authoritarian communitarianism, but the normalization of prostitution creates a bunch of straightforward externalities that we should be able to talk about, from economic pressure on people disinclined towards sex work to the inevitable screening failures that bring minors into the industry.

Of course, you could make this point effectively just by explaining to the preceding commenter what an externality is, since the idea is fundamentally about the damage consenting counterparties can do to the surrounding community.
