The problem is, I don’t think any woman sells her body willingly, whether she appears to, or thinks she does. All are victims of male privilege. And yes, that goes for Inara in Firefly too

And if slavery doesn’t work as an analogy, what about human sacrifice? Some victims willingly allowed themselves to be sacrificed. That didn’t make the practice right.

I not only want the future to be better, I can actually see it happening. We are, as individuals, better off than our ancestors (current tory scumbag shenanigans notwithstanding). History has been a (mostly) progressive process. So for an imagined future to be regressive strikes me as a failure of the imagination. Prostitution was simply the most egregious symptom of that in the book.
