They have legalized the activity, but they seems to not want to get involved with the operational rules.
To borrow the drug comparison from further up, this would be like legalizing hard drugs but not putting down any ground rules for labeling or certification of content.
Consider alcohol. Most places it is legal to sell, but there are still regulations in place, and hopefully policed, detailing when and to whom it can be sold.
When people talk about legalizing drugs, they likely envision a similar system of regulations surrounding it.
Similarly regulations have to be put in place regarding working conditions etc for prostitutes as part of the legalization process.
Removing the sex aspect and the article reminds me of some of the shit the construction business has with exploiting foreign workers.
I recall reading about people living 6 to the room in what was supposed to be a single occupancy apartment etc.

That's exactly the problem. Campaigning for tougher laws against sex trafficking is great voter bait, but actually enforcing the existing laws? That costs money!

The women go there knowing that they will trade sex for money. What they do not know is how difficult and exploitative the work is.
