Go ahead and ban plastic guns, sir. By the time the average law-abiding human has had his freedom to own firearms reduced to having to print a plastic gun, he will not care if it is legal or not.
I don't need to print a plastic gun but I will still be downloading the plans when they are available. I have my metal guns and I prefer those. However, if at some point in the future a plastic gun is the only thing standing between me and freedom from tyranny, I will CTRL-P my way to freedom.
