I would not take advice from someone who runs an org called "People Against Pornography" and basically sounds like a prohibitionist.
Something which has been seen in some countries is that when they had prohibitions, people couldn't report it to the police, and the police might even be part of the problem, they might abuse someone in exchange for "overlooking" it.

"But keeping sex work customers criminalized keeps in place many of the harms of total criminalization. The sex industry must still operate underground, which makes it more difficult for sex workers to work safely and independently."
"A recent study of prostitution laws in European countries found full decriminalization or legalization of prostitution linked to lower rape rates, while countries that instituted the Nordic model during the study period saw their rates of sexual violence go up."
