But removing the ability to kill oneself by installing a net removes the possibility. If you're going to kill yourself, you don't try to do it via a means that has no chance of success. With a net installed, all the chance of success is removed, so people aren't going to try it there. You don't hear about failed suicide attempts jumping off a car onto grass. And I've battled with severe depression and alcoholism in my past. I spent nearly half a year thinking I was going to end my life every day and instead crawled into a bottle. You're right in that we're not thinking rationally, but at the same time, irrational "I must escape" thoughts also don't drive you to say "hey, I know, let me go way out of my way to attempt suicide in a way that I know will not work."

edit: if anything, more people will probably jump, but not to kill themselves. thrillseekers might do it just for the hell of it (despite the fact there will likely be a big penalty)
