Fair enough. (I intend to find a good & recent survey paper still but chores have come up, so it'll have to wait a few hours.)
> Have you.. talked to any trafficking victims? Any sex workers?
Not personally no, I only know what I've learned of their positions through articles I've read and documentaries I've seen. Why, have you?
> Drug addicts would like drugs to be legal, oil barons would like there to be no natural protection laws, prostitutes would like prostitution to be legal.
Why are you equating prostitutes with oil barons of all things? This seems like a list of people whom are often viewed poorly, and I can only infer the rhetorical function here is to tar prostitutes through association. Which makes me doubt the sincerity of your concern.
> And what do you think has changed about sex trafficking and prostitution in 11 years?
I'm sure the state of those things as they relate to the internet has shifted, but not importantly what I was suggesting was the understanding of this field of research has probably changed dramatically in 11 years.
> Right because you squash the market.
What market has ever been squashed by prohibition? Alcohol wasn't. Drugs haven't been. Prostitution hasn't been.
> Arguing your trafficking victims should get better health care is worse than just having meaningfully less trafficking victims.
There won't be fewer trafficking victims, or other sex workers who are victims of abuse, we'll just have disclaimed responsibility for them by declaring that it's illegal and excluding them from polite society. The abuse we'll continue, and the comfortable can pretend it doesn't exist because it's been brushed under the rug.
Additionally, it absolutely does matter if we can provide services. For the example of drug use, the appropriate healthcare (eg Narcan, needle exchanges, treatment for addiction) can make a night and day difference for survival. Sex workers would be safer if they weren't stigmatized and so more likely to be believed if they ask for help, if they were able to operate in the open with hired security and vetting processes, etc.
