By prescriptive you mean locking the stable door after the horse has bolted health and safety legislation?
Whilst health and social services are readily available, sex workers are required to undergo regular health checks at the government's expense. Brothel owners and room operators often require health certificates such as the SERVSAFE test before employing or leasing rooms.

The Dutch are just a lot more pragmatic about sex and drugs than most countries. Which is why you have transparent prostitution and cannabis cafes (coffeeshops). I mean people are going to do it anyway, we might as well monitor it type of thinking.
Like many people have mentioned Amsterdam is a whole lot more than the red light district, which incidentally is a lovely area in the day time, canals and gabled houses (and really quite small). Prostitution has been going on since the city was founded cos of the maritime tradition. It hasn't always been legal of course.
British male stag do's have the worst reputation here. I fucking hope they ban those awful beer bike contraptions soon
Thing is, any guy going to step inside a prostitute's room in the RLD will have 10 thousand tourists looking on most probably taking photos

Yes, I think it's grim. And so are those kind of stag do's. (anywhere!). I have no moral qualms though about a woman choosing to go into the sex trade.
Incidentally, watched a Stacey Dooley doc. on Prague stag do's on Youtube.. Ugh.
