It's about taking advantage of it, and showcasing how absolutely asinine it all is.

A ghost gun is a gun that's made on the street, or off record, like a 3D printed gun (Or two wooden boards and and some rubber bands.)

Someone recently 3d printed like 38 guns for 5$? 3$? each, and sold them for 5k to a buy back program. That's absolutely what someone should do. Take advantage of it.

So they said they would stop buying 3D printed guns.

Which leads to the above, can that lead to them denying that 3D guns are ghost guns?

It sets an interesting legal precedent, and sometimes, we need to put the target on our back, in order to get change done. Not everything can be done from the protection behind our screens.
