There isn't really an option with no costs to them, though, is there? You have people who are attracted to children, and people who have abused children (maybe or maybe not while young themselves). Child abuse gets near-universal bad reviews, so you're left with a trolley problem in the end where you need to find the least harmful, most fair solution. Someone is going to pay something.

You can make a deontological argument that anything medical is off the table, I guess, but deontology feels very unfair when you're on the losing end of it - we brought in MAID to fix that, and homeless people are still often violating the law just by existing literally anywhere.

That's entirely my point.

It doesn't treat it. Not really.

It suppress urges. Chemically.

There are other options.

Counselling, therapy, groups like AA, all the examples I gave in my first post. Those are very available to other offending types. But for an SO they don't exist, or would be very expensive, or difficult to navigate because of the stigma.

There's nothing to make someone not gay, or not straight,or not attracted to children. But there are means of regulating thinking, compulsions, urges, etc.

The barrier is the stigma for treatments.
