[Do you disagree that it's sometimes the logical action for an individual to take?]
I don't disagree that it's sometimes a logical action to take. This is more of a rule to ban those "Kill yourself" assholes, but then again they could be banned by some other rules for saying that. That being said, I think there's always at least a small degree of hope in your life. Take yourself for example. Most people would say you're living a failed life and in some sense you are. But at the same time you've made more difference than most morons who work 9-5 jobs do.
There's another reason. I'd much prefer people who wanna commit suicide going ER. It would kill some Western scum and give more attention to the site. Them offing themselves in empty rooms, not so much. But I can't put that into rules.
