Driving's intent is not to kill people. It is to transport people from place to place. The point is you can't (or rather, shouldn't) curb drunk driving by prohibiting cars.
Guns only intent are to kill or seriously injure. You may argue about what they kill (IE guns used for hunting), or why they are used to kill (home defense), but the point is that they serve one purpose: to kill/seriously injure. And you can reduce that number massively by.......restricting access to guns.
I noticed, btw, that you used the number of "mass shooting deaths" as your "small, not statistically relevant" number. But it's something like 20k gun deaths in 2020, and those are just the homicides. Suicides push the total number to 45k. And the suicides are important because our rate of suicide is higher precisely BECAUSE of guns, because suicide is an act which can often result from a moment of desperation. The minute you have to plan your own death, suicide rates go down - but if you can grab a gun and instantly kill yourself, it's easier to give in to that singular moment. 79% of our homicides involve a gun, compared to 4% in the UK, 13% in Australia, etc. We had 16k homicides in 2018, compared to a little over 800 in the UK, for a 4x higher homicide rate. The countries above us in homicide rate are third world countries and autocratic states with little to no gun regulation.
Like, this isn't difficult.
