The question I pose is, what are the primary uses for guns and their viable alternatives, if any?
At which point you're having the entire gun debate. Are more criminals deterred when it's more likely their victims are armed? Does that also work at the national level, in that it's easier to raise an army when more of your population already knows how to shoot, so other nations are less likely to attack? Does it deter domestic tyrants who know they would have to fight an armed insurgency, or give citizens more confidence to make just demands of a corrupt state? What's the economic value of the jobs created by that industry? What's the community value of it as a sport? Are there ways to reduce the harms without prohibiting anything?
If you want the answer it's necessary to have the debate, not pretend there is no debate to be had.
That's the point. We have that number of vehicle fatalities. We don't ban cars, we improve safety. Air bags, concrete barriers on divided highways, etc.
There are a lot of things we could do to reduce the number of firearms fatalities that we aren't doing. Mandatory firearms safety classes in high schools would reduce the accident rate. The government actually prohibits normal citizens from buying body armor, even though people who know they're at high risk of being shot could otherwise buy it and cause them to be less dead. A huge proportion of the shootings in the US are drug and gang related, which means if we addressed those problems better there would be less shootings.
But it's politics. Their intent isn't to solve the problem, it's to whip people into a frenzy so they'll vote for one party or the other.
