As I said in the last discussion about this [1], I think outright banning just leads to worse outcomes, so you need to find a medium where you can minimize the abuse while still allowing people to get their hit enough to not go seek out unregulated forms.

I'm not fond of it either, but I don't have a better answer that doesn't seem like it's going to lead to worse outcomes.
