Perhaps if you really want a santized version of reality and still seem to visit Europe, you might dry Disneyland in Orlando. Most of the prostitutes and dope dealings are done most behind closed doors there. Nothing broadens your horizons as much as international travel without those disgusting habits and laws and customs of the local inhabitants.

They did that to the Zeedijk (top of that area) 20 years ago. It used to be a really bad neighborhood, but has improved immensely. So I have confidence ;)

The search for a loophole in the coffeshop-laws is for a big part because Amsterdam has a few highschools right in the centre of town. So the Bulldog (first coffeeshop and best known by tourists) on the Leidseplein would have to close down since the Barlaeus Gymnasium is right around the corner.

Its also no coincidence that the Amsterdam red-light district is prime real estate with lots of developers salivating over the prospects of those buildings opening up. The question is, what will replace it? more souvenier shops? As for safety, the area is a bit sketchy at a certain hour, say 5 am, when I stood on the achterburgwal, waiting for someone to open the gate so I could do make-up for official zwarte-pieten. Happpy Sinterklaas everyone.

I went about two or three years ago as well. It seemed clean and safe to me--and utterly boring, compared to other cities like San Francisco, Hong Kong, New York, Bangkok, and Shanghai. If you're not looking for cannabis or sex, or aren't of Dutch descent, I frankly recommend pretty much anywhere else. The architecture and museums don't make up for the bland food and monotony.

I noticed a couple of different red light areas--one of them held noticeably less attractive and older prostitutes, which I suppose is what you saw. Another area apparently had the more attractive (and presumably more expensive) ones.
