Can you make someone just not sexually interested in something they find arousing?
No, I can't. Doesn't mean that we (as a society) shouldn't be working on finding ways to do it or finding alternative solutions. And it's necessary to acknowledge that what we have now is not good enough.
those therapies also tended to involve some form of harm
They probably did. But nobody here is claiming those were good or helping the patients either.
I wouldn't consider 1, 2 and 3 asymmetric, they are just patterns.
