Earlier quoted context omitted.
Do those factors have the same meaning when someone would rather not be e.g. a cleaner or an orderly at a nursing home? Those jobs are physical and not so pleasant. They pay much less than prostitution. Yet, many people are so employed.
Prostitution is still about selling what is most intimate, not really the same. Also, how are we supposed to reach gender equality if one gender's body is for sale as a matter of routine ? Note that I still agree with your point on being a cleaner, that's why I think universal income is a good idea.
At the end of the day when an adult makes the decision to do a particular job because it pays better than the alternative we can't automatically count them as a "victim". It robs people of their agency and infantilizes them.
