> .. if addiction is the only remaining problem with them, should we care that much?

I think we should because it’s undignified to have people who want to stop taking them but are unable to resist the compulsion. I feel the same way about basically every addictive substance. Even if it was freely available and risk-free I still think that being trapped in a cycle of use and withdrawal is such an affront to someone’s dignity that we should still try to prevent that.
