I think this view falls short because it seems to count the chances of someone making an uninformed mistake as an acceptable consequence of preserving individual choice. Personally, I can't agree with this view. I often state that my desire is to protect and preserve life when it comes to suicide and am met with backlash over "inserting myself into other people's lives." When the reality is I've been close to several suicides (due to my community role) where the general community consensus was that the person was dealing with a complex mental health issue and the medical system more or less failed them.
I don't propose to win anybody to my side, but I think the whole topic requires a lot of nuance and shouldn't be simplified.
