If you feel like money is a corrupting factor then don't hire a sex worker.
For my part, they're some of the chillest people I've gotten to know, and they're not hurting anyone just by their existence.
Not to mention that literally every action that even tangentially ostracizes or criminalizes sex work has horrifying blowback against victims of human trafficking and against sex workers in positions of vulnerability.
The Craigslist purge for example led to waaaaaaaay more dangerous working conditions for sex workers since it removed one of the few tools they had to reliably vet possible clients.
There's literally no approach to sex work other than just letting them fucking be that doesn't end up causing exponentially more harm to completely innocent people than could ever morally justify doing anything except just letting them fucking be.
