What about the idea that attraction to children itself is a social construct and can be changed with the right attitude? I don't believe that, and I assume you don't either, but if so I'll note that you are assuming immutability in one place but downplaying it everywhere else.

Evo psych has a pretty good story to tell about women, sex, and false pretenses. In the EEA, a woman's #1 priority in sex is finding a man who will stay around and help bring resources for the child. Not proven, but pretty likely. You can solve slut-shaming but signs suggest the more fundamental situation will remain.

I agree that a lot of these things could be changed, but I think some would be going uphill. "Free love" for instance is a hard sell. We got lots of it around 1970, but people (especially women) pulled back because lots of them didn't like it.

I think broader society -- even the liberal side -- will look at the social changes that the pro-contact position wants and see a list that's kind of tailored to allow adult-child sex. Seeing such a list tied to people identified as pedophiles will reduce its credibility. They'll take a broader view of the matter, and their list of desired liberalizations will not match yours.

My hunch remains that if you really freed children sexually and removed all their hang-ups and inhibitions, they would use the freedom mostly for prostitution.
