This reminds me of the discussions we used to have in high school about how we should ban all writing implements because they can be used as weapons.
Which is as silly stupid as it always is, because it's a hell of a lot harder to kill someone or yourself with your average pen or pencil than it is with a gun. Like, drawing on yourself is hella' unlikely to cause you to bleed out. Shooting yourself in the foot is a decent way to lose a foot and possibly too much of your bleedy stuff.
Unfortunately, when it comes to firearms it's
specifically because of ease of use and deadliness that it contributes so much/disproportionately to violence or suicide. Consistently people find slowing the purchase process or removing guns from the situation helps mitigate violence or suicide (attempts) at rates in the same ballpark as anything in the psychological or sociology range of junk, due in no small part because the recommendation from either of those likes to include things like "don't have things it's
easy to kill people with in close vicinity of people who may be inclined to hurt themselves or others, seriously, holy shit why are we having to say this". Even when it doesn't reduce rates of violence or suicide attempts, more people survive the incidents. Reducing access to purpose built murder weapons is, in fact, one of the correct ways to cut down on the amount of people that die.
Oddly enough, having a device purpose built for killing on hand (or near enough you can easily get to it while pissed off) enables greater degrees of killing. You'd think that'd be as stupid obvious as a designated driver
not letting their drunk compatriots hold the keys or something, but apparently it's not.
