Maybe. I think automobiles is better because preventing driving prevents automobile deaths, so there is a pretty reasonable case to make that it is a necessary and sufficient measure to end deaths from car crashes. Pretty hard to rebut the automobile analogy, isn't it?

Gun violence is illegal and quite significantly committed with illegally obtained guns and particularly pistols. So banning or increasing legal controls on rifles (for example) would not be an evidence based policy for reducing the largest sources of gun violence. Unless you are drawing parallels with the relatively low effectiveness of vaccines, but even then I don't think vaccines are quite that bad :)
