I think it will reduce human trafficking in that it would be much easier to monitor for human trafficking whereas in the past with some sort of grey-zone criminalization, you would have to actively first detect for sex workers, convince them that you are not arresting them, and then figure out if there are human traffickers or crime involved. Its one less step if you can more easily monitor and the sex workers can speak freely to police. In fact I'm more about how they treated sex work in several historical governments in the past and that is only government-operated brothels are allowed.
