Yes, but ideally there should be regulation to prevent pimping, predation, trafficking, and STI spread. At the very least, decriminalization protects sex workers from fear of prosecution preventing them from seeking healthcare, legal help, etc.
Trafficking is heinous, but it also gets irreverantly thrown around as a whataboutism by people who are against it for personal instead of rational reasons.
The root of the problems with sex work, as always, is tying means of survival to productivity, which I am against both personally and rationally :P
