Oh good grief, trying to shove this back into the Limbic emotional brain, serves no purpose, in examining the realities.
Actions surrounding prostitution are in the criminal code because it was at one point felt that there was no other forms of protection for the front line sex workers, as it is NOT a recognized industry job.
Make it a recognized job, and all acts that are now deemed criminal will fall away.
Distillers once used to be designated "criminals", until distilling became a legal industry.
Decriminalize the acts surrounding it, without making it a job industry, means there are still NO protections for front line sex workers job wise, as there are no regulations on the industry.
We don't send other workers out into unregulated job situations, and we can't send sex workers either.
It is just that simple.
