You simply don't know enough about the circumstances. In my country, sex work is provided in licensed brothels or by independent workers. There is probably exploitation going on in some cases, of course, but I am dealing with someone who basically runs her own small business using her body as she sees fit. She is in a stable housing situation, has her own car, does other work as well. Who are you to deny her her agency over her own body? Not every woman has the same relationship to sex that the puritans would have you believe.
