This will be a hot take for some but people opt out of a life that's pointless, miserable, painful, and hopeless. Preventing people from access to methods of opting out is but a palliative measure.
Sure, people can be dissuaded from making an attempt by making it difficult, but isn't it far better to address why people want to opt out in the first place? And of course, it's best to do both: prevent people from making attempts, and address any issues they might be having in their lives. Even better, provide "end-of-life" care for those who really have had it enough for whatever reason.
Why lock people into a miserable existence anyways? Someone might have been prevented from opting out, but if conditions don't change (and no, it doesn't always "get better"), you've got a person will just resent even being kept alive. What good does that do?
Now, for the trash take: I suspect suicide is a problem because suits can't make the line go up if people are killing themselves. The suits need people to consume and not kill themselves.
