These things continue until we criminalize it.

Slavery kept going until we said that's illegal.

Child labor kept going until we said that's illegal

Putting heroin in baby food formula kept going until we said that's illegal.

We don't defer to the free market for everything.

Nobody is like, well child porn, I guess there's a market demand for it so it's right over there with the magazines

It is neither strange nor unusual to value things more than the freedom of the market. We do it all the time.

We should do that with societal harms and not just individual ones. Criminalizing obvious crime shouldn't be some kind of wild eyed fantasy. It should have been done 150 years ago.
