Yes, capitalism is a pretty new concept also. The two go hand-in-hand.

But never before in history have we been able to copy media ad infinitum for practically zero time, cost and effort. It's always required time, an educated, talented person to copy, or resources that had a real cost.

In the case of the 3D printer the only real expense is the plastic used to print the object, which is awesome only for those who manufacture the materials.
