I think it is exactly the point, hence not being insulting about sex workers, but about mocking "clients", red capped MAGA crowd here. I may be wrong, but at least it's the way I read it.

Clients may indeed think they are special, that this dance is dedicated to them not because they paid, but because they are special. When in fact, she's doing it because the deal was about money, as a job.

The dancer is not the point here, the dudes are, thinking they are treated in a individual and special manner. Isn't it?
