Like Canada and most European countries, this should be legal and regulated.   It is working in all those countries and see why not here.    It is all those religious bigots standing in the way.

But it actually costs law enforcement (aka taxpayers) on average $2600 to make one arrest. That doesn't include everything subsequent to arrest. So I'd argue that it's more of a political stunt than a money grab. Unless, of course, they can throw RICO at someone and seize their assets.

It's also an easy gig: sex workers don't carry guns or pose danger, are usually scantily clad, and in some places the cops can partake of the offerings to their heart's content before making an arrest. Win win for them.
