And just as I am sure you agree that the coercion of men into these hard labour work gangs is wrong and the people doing it are exploitative and should be punished - so should the Johns and pimps exploiting women.
Oh I completely agree with this. Anyone who coerces someone else into doing anything, be it regular work or sex work, should have the full force of the law come down on them.
I'm not for one moment pretending that most sws have the choice of either being eg a highly paid lawyer or an escort. It's quite clear in most cases we're talking about women who have limited choices. It would be either working long and hard hours in min wage or fewer and more flexible hours as a sw, but with the risks and caveats I mentioned above.
Still, the fact that poor people exist and by definition their choices are limited, is not the same as actual coercion.
The reality of life is that from the moment we are born, unless someone provides food, clothing and shelter, we wouldn't survive. That is just reality. It's a sad state of affairs when people have to make difficult choices in order to survive, but you can't compare that to real slaves.
The woman doing sw is no more coerced than the man cleaning the streets through the night in all weather conditions. Which is to say they're both doing shitty jobs* in order to survive. But there's no coercion involved.
*each one is shitty in their own way. Before you jump down my throat I'm not saying street cleaning is exactly like sw.
