Sure, and sensible things like barriers at bridges makes a ton of sense because doing that doesn’t negatively impact anyone and merely gives people more time to rethink their choice.

That said, even with those safeguards, tons of people kill themselves. I had a friend do it by hanging, others use drugs, and some use cops.

If we look at statistics, the US has 15.6 suicides per 100k, compared to 18.4 in Belgium, 12.9 in Germany, and 16.6 in France (not trying to cherry pick here, please look up the stats yourself). Each of those countries has (largely) banned guns, yet the US’s numbers aren’t all that different, so surely guns aren’t a major contributor here.

What we need is to address the core issues here, such as access to mental health resources, more social interaction, etc. Banning guns isn’t going to meaningfully impact suicide, it’ll just shift the statistics to other methods and maybe delay it a bit. People like easy solutions, and treating the symptoms is very attractive, but it’s not a real solution.
