I honestly think the majority view on suicide is not that it's painless or easy but that it's inherently tragic and not to be celebrated or romanticised, and fwiw this is the correct view.
As for the paragraph you quoted, I've not taken it in context (though tbf I'm already aware that enthusiastic antinatalists are the most tedious people in the history of the internet so i don't feel the need to read it in full) but whilst i disagree with the language used and would take issue with his view that suicide is easy and painless he's not wrong when he states that methods are there, available freely, and people do use them, daily. If you haven't been able to summon the courage to hang yourself that's fine, there's nothing wrong with admitting this, i haven't been able to do it either, but for goodness sake can we please stop pretending there is a huge conspiracy against individuals suiciding when there clearly isn't, literally all of us are at liberty to kill ourselves. Many, many people have done exactly that without a pro-suicide government policy being in place.
As for people's views on suicide, imo, yes, most people do share the view that suicide is a tragic action but that isn't mutually exclusive with the view that it's painless. I believe that some people share both of these views simultaneously.
Also, I genuinely fail to understand at how all of us are at liberty to kill ourselves. In my case, yes, I will admit that methods like hanging still exist but the issue for me is that I'm unable to hang myself, not because of lack of courage, but rather because my autistic brain makes me incapable of understanding how to tie knots. I just don't see how I'm at liberty to hang myself via hanging as my brain prevents me from understanding the fundamentals of it. Sure, there are other methods like drowning or jumping but I'm not sure I'm at liberty to utilise these methods either because, as for jumping, there isn't an unmonitored high place near me that I can jump from and, as for drowning, I run the risk of somebody spotting me during the attempt. Additionally I have to deal with controlling parents that would near immediately call the police to find me the moment they find me to be missing. If I wasn't stuck with controlling parents, I feel like I genuinely could say that I have the liberty to kill myself and that's exactly what I would do.
Maybe most people are at liberty to kill themselves but fail to do so because of lack of courage but, in my case, I genuinely don't see the liberty that I have to kill myself due to my personal circumstances as well as my neurotype. I'm going to clarify here that obviously I'm not asking for ways in how I do have liberty to kill myself as pointing this out is against the rules. I'm merely expressing at how I think that I don't have the liberty to kill myself. I may be wrong of course but this is how I feel.
Also, you could potentially argue that I'm at liberty to kill myself by pointing out something that I failed to see for myself but what about the rare cases where somebody is unable to kill themselves because they are paraplegic or otherwise limited by their body to kill themselves? I'm curious as to what you think about these cases
