Forcing someone to live when they wish to die is no better than killing someone who wishes to live. You are welcome to try to talk them out of it but have no right to interfere with their choice—whatever it may happen to be.
Suicide prevention is not "forcing someone to live". Suicidal thoughts are usually transient and any delay in suicidal action allows the person to seek help. Like I said in my first post, reducing access to means an methods is only part of the package that we need to be providing.
You keep trying to make this point: you keep trying to say that suicide is a choice that people make. I'll try again: it often is not a choice that people make. Please just go read the research. Here's a tweet about "Rapid Onset Despair": https://twitter.com/ProfLAppleby/status/939820235946971138
You especially need to pay attention to intoxication and suicide. Or are you saying that an impulsive decision made when very drunk is no different to a considered decision that is stable over months made when sober?
> no right
Since you mention rights, people have a right to life and suicide prevention respects that right. It respects that right in a way that wide-spread gun-ownership doesn't.

I live in England and the Mental Health Act and Mental Capacity Act specifically give HCPs the right to take away people's choice in some limited situations. I don't know where you live but you almost certainly have similar laws around substituted decision making.
You're making the mistake of thinking that someone makes a choice to die and is then determined to carry out that choice and will use rational thinking to chose the most lethal method. It's often not a choice they make; they're often not determined to die and people usually do not make efforts to avoid being found; choice of method is complex but tends to focus on what's easily available and quickly fatal.
Have a read of The International Handbook of Suicide Prevention, edited by Rory C. O'Connor, Jane Pirkis, because it covers all this in detail. Or you can read the NCISH research. Or you can read Professor Nav Kapur's book Suicide Prevention.
