Too many guns in circulation in America now to begin control.
That horse has long bolted.
Not really, limit the ammo, make it harder to buy additional guns, limit or ban access to Semi and Automatic guns. Let people have a hand gun, shot gun or single shot rifle. They don't need weapons designed for war. It is of course not easy to remove 300,000,000 guns in fact it is likely not possible but there are other avenues that can be followed.
Your reasoning is the American way, it can't be done so lets not bother. The reality is the NRA has made it impossible for there to be even discourse about some sort of gun control yet there are plenty of options to try if they really want to.
