How about: "In some countries, sex work seems to be illegal and problematic. But in other countries, it's regulated and successful.".

My take is similar to yours, I'm just communicating to the original commentor that the societies where sex work is legitimate, regulated and safe is a minority compared to the societies where it isn't.
Thinking about it, that's a good point. "Unforced" (eg voluntary or better term) prostitution seems like it wouldn't have anything to do with "human trafficking", as they'd be kind of anathema to each other.
Now, it is “some countries”?
