Sex workers are exactly what they don't need. That will push them even further down the rapidhole because that's exactly what they think about woman, nothing more then sex objects.
Back in the day we had conscription for the army, and this resulted in mixing people with other people and spend time with them. It was great to kill barriers created between rich / poor / racist / not racist / political andy's. Because they all where forced to work together u suddently realized that your buddy in the army u spend 2 years with and is black actually isn't that bad of a guy. Or your right leaning voter u though was a nazi was actually not that bad of a guy.
The same shit should happen for incels, instead with incels let them go into therapy, let the therapist move them into somekind of charity thing they have to attend towards that is dominated by woman, and let them have to work with them, eat with them, share there life with them etc. And sooner rather then later they will realize they are no longer part of that incel club because they are just deranged with the reality.
It also kills there isolation and they can make friends or even relationships out of it.
I found a movie with this concept really good, that was called american history X. this main character absolute hates black people, grows up in a culture where they all hate them, wars them and gets into jail as a result. And guess what happens? his best buddy because a black guy because he's forced to spend time with him. He returns to his nut neightbourhood and realizes how fucked in the head they are.
