I get what you're saying, if we're talking about ultimate bottom line of deaths. Could we also bring in junk food, as parents set their kids off on bad diet choices for life on some cases... sugar is addictive too.
Cars provide utility. As others have mentioned, in some (most?) Towns and cities, they are near enough essential, if yku want to function in modern society, with how its setup. Takes kids to school(s), then get to work for 9 in bournemouth... Good luck with that if your house, school and employment isn't within a mile or two of each other.
Despite what some Americans may think, a fire arm is absolutely not an essential utility. I certainly don't have a clue around how strongly many Americans feel its their right and why it shouldn't be changed, so I'm not saying it's easy, as these things tend to be complex on many layers, which without living there, cant be fully grasped/empathised.
To me it strikes me as too much feeling over logic, which is always shake ground for keeping/creating laws... very strange imo, for a so called leader of civilzed, first World countries. A relic from centuries ago, that surely should have been 'amended' along' with many other dubious customs and laws 1st World countries have abolished over time. Demand the Right to hold a firearm in 2023... seriously.
