- Sex work is much more dangerous because it is illegal
- Legal sex work could lead to increased trafficking when there is so much unmet demand for legal immigration, but abundant legal immigration would solve that
- The people currently seeking out illegal sex work, or seeking it out in countries were there is more violence against women in general, are probably much more prone to violence. Increasing the size of the industry would result in a "regression to the mean" among johns
The porn problem is a bunch of people subtlety rewire their libidos in anti-social ways over time. That is involving orders of magnitudes more people than those that currently beat sex workers, and men and women alike (as the interview makes clear). A good legal prostitution system would have be:
1. Still quite expensive
2. No "pimps" or anything of that nature
3. Sex workers higher their own private security, run their own brothels, little reliance on police (who are likely to continue to be misogynist fucks regardless of how the law changes)
Basically poorer men, instead of going to cheaper brothels where the workers are treated worse, would have to "save up" for fewer trips to still-expensive establishments where 2 and 3 are still abundantly true. High American equality does also make this a challenge, for sure.
