Whether we like it or not, prostitution is a profession. As such it should be recognized, cleaned up, taxed and protected in that order.
“Inspectors will prowl the streets and any prostitute caught without a ticket [that can be bought from street vending machines] will receive a warning for a first offence, but after that faces the possibility of a fine or a ban from practicing prostitution. […] Along with the location providing a certain amount of privacy [closed off parking lots], they also come with alarms a prostitute can trigger if she gets into trouble. ”
My only observation is that the article implies that only women prostitute themselves.
