I sympathize with the call for decriminalization.

Still, in the case of sex work, I think you are simply wrong. Your overall sketch is the "movie version" or police/puritanical version of sex work, a version that equates trafficking and voluntary transactions (not that those transactions can't exploitative in other ways). The majority sex work isn't filled with violence except on the level of the literal street. Notably, my friends and acquaintances who used Craigslist back in the day didn't deal with any pimps and a moment's thought would show pimps are only needed when someone sells sex at a physical location.

Also, afaik, onlyfans is a virtual only platform so workers there face the same physical dangers as people on zoom calls.

Drugs is a more complex beast.
