Agreed! I actually learned about it here: Germany installs prostitute street meters for sex tax. I think it would really be better than the traditional street-walking activities but it's still alarming in some ways that it could really encourage some to do it since it's legal already and the activity will be publicly displayed even to those young individuals with innocent mind that could possibly generate the idea in their minds that such thing is just fine. Can you just imagine what would possibly happen to the next generation with the present system?
