Earlier quoted context omitted.
No one should feel shame at having a toilet at the office and needing to pay someone to help clean it. Everyone should feel shame at coercing a person who would otherwise not have sex with them into having sex with them. Buying someone's labor is different than buying their bodily autonomy and consent to sex.
This sounds more like a moral judgement. Labor is labor, you don't get to redefine labor just because it involves an action which is very controversial. What really matters is the safety of the person(s) involved. And yet, there are plenty of occupations where safety is in question.
The question is whether or not we want to be a society that views people's bodies and sexual access to them as a commodity to be bought and sold. I find it baffling that anyone would laud this condition after giving it a few moments of compassionate reflection.
