All that removing method options will be doing is making suicide unnecessarily difficult for people and will mean that people have no choice but to resort to more painful and risky methods. It wouldn't stop suicide. People will always find ways to ctb no matter what, people ctb even before the internet existed.
The truth is that suicide is simply a part of life and this fact should be respected. We will all die anyway after all so there will always be people wishing to exit at a time of their own choosing. There is no benefit to trying to force people to stay in a life that they never asked for against their wishes, and it really is cruel to want to make death as horrific as possible for people. Pro lifers are disturbing, they should have no right to interfere in people's end of life decisions. Not everyone wants to suffer until old age.
