Not only can you make a gun easily, 3d printed or not, you can even bootstrap (I don't just mean handload) ammo now. Criminals will hella have hella guns and the cat is too far from the bag to put it back. Even individual manufacture isn't a real hindrance as long as your network contains someone who can make a gun.

The old Improvised Munitions handbook has instructions for how to make a "zip gun" with little more than pipe and a nail. Guns are easy. Safe, reliable, long-lasting guns require a bit more work.

Guns are not hard to make yourself, now, if you have a little competence with tools. In ten-twenty years, you'll be able to print off as many as you want with absolutely no technical skill.

Stopping people from killing others with guns is a cultural and social issue. Trying to fix it by blocking access to guns is an ever-more losing strategy.

There are lots of examples of countries whose ban on guns work and whose ban on drugs doesn’t work. Therefore it is a bad argument that guns can’t effectively be banned since our ban on drugs hasn’t worked.
