Don't really agree with this. If you look at it on an individual level, there's a case for it, but on a social level, it's dangerous. Individualist societies look for individual solutions even if the problem is social. There are problems that can't be solved with any sort of medication, therapy, etc, because the cause of the problem isn't with the individual. It's impossible to know for sure if any kind of social change would fix her problems, but if suicide is simply the go-to answer when such a problem is encountered, then we will never know. And once this becomes normalized and people start accepting it as a viable solution, then it's going to be a lot harder to materially improve things for people in these situations. Often it's only when people see that there is no individualist solution that they start thinking in terms of systemic changes, and if there's any kind of "solution," no matter how horrid it is, they'll turn to that first. I don't want to create a future where, "I've tried everything I can to fix myself and I still feel like shit," is met with a polite and friendly, "Oh, well have you considered killing yourself?"
Suicide is violence. Self-harm is harm. It's nonsense to describe a process that kills you as "safe." I understand that many people view it terms of rights or personal wills because those are prevailing ways to look at things, in individualist cultures. But life is inherently valuable and if someone thinks otherwise about their own, then they are wrong. I would make an exception for someone with severe, incurable physical pain, but while mental pain is just as real and valid as physical pain, the way it functions is more complex, and so I'm skeptical that it could be declared "incurable" to a sufficient standard, especially if solutions aren't limited to the individual level.
The fact is that we ought to be striving to accommodate as widely diverse minds as possible. Both because it's the right thing to do, and because diversity is valuable, and people who see things differently may notice or understand things that others don't. If the diversity of minds starts to narrow, I'm concerned that it will continue to narrow until neurodiverse people are effectively eliminated from society, or be isolated without community, as more and more pressure builds against anyone who doesn't fit the mold of a productive worker.
