If you “reduce the demand” you will not reduce sex workers real need for the money, you will just make their lives impossible.

“Occupations are at the heart of sex workers’ rights movements. Think back to the Lyon occupation in France in the1970′s. Taking Times Square last Saturday was a full circle moment, given the history of sex work in Times Square, and the joined forces of corporate and political interests that have displaced sex workers from not just Times Square but any public space. For sex workers, occupying public space is about economics as much as it is free speech.”
