Comparisons between gun deaths and traffic accidents is ridiculous. Transport is an essential human need.
My point is that we make this calculus every day, and accept risk where we find it useful, even though the cost is staggering. I drive a car. I have never owned a gun, and probably never will. I have reduced the risk that I will be shot by some percentage, but I still take my health/life in my hands almost every day by getting behind the wheel of a car. I also have a set of knives, and any number of other conveniences that introduce a level of risk that I accept, because they make my life easier or better or more pleasant.
We cannot pretend that we don't take risks --and accept a very high price-- for the sake of convenience and for a better life for those who don't pay that price. We draw the line at guns (and rightfully so, in my mind) because they have moved in the opposite direction, where they are no longer the essential need that cars are today. But we do so only because we can give them up without sacrificing convenience. We seek to do so for practical and pragmatic --but not moral-- reasons.
