I can see the point if it is on a grand scale with thousands of tarty looking women next to a school, but Montera Street? That's city centre stuff.
It sounds like abolitionist stuff creeping in under some concocted umbrella. They would be far better tackling trafficking directly and giving more rights to prostitutes. Street prostitution has never been quite legal in Spain as far as I am aware so better standards for prossies and punters would be a natural good move (although I think there is a place for lowlife SWs in certain areas where they are not a bother to others or better-dressed SWs hat are not an annoyance to others anyway).
Goya and Picasso would be up in arms (probably the arms of a nice prossie or two of course).
