Can a rocket be used to cut your food, take you to the supermarket or power your car?

I'm completely against regulation of any sorts on 3D printing, but you have to admit there is a huge difference in purpose there.

The same states that want to regulate 3d printers and force you to register them and install only software that will prevent you from printing anything that even looks like a gun part are also the same states that have been trying (or succeeding) in enforcing those same sorts of broad and dubious regulations on firearms too. When you think of states whose legislatures think collecting and shooting guns is an acceptable hobby, California and New York don’t exactly top the list.

Oh, I totally agree. I always see this as evidence that the terrorism threat is overblown, if it were really as large as we are led to believe the number of successful attacks would be far higher than it is.
