The U.S. is using all of these measures now. First, guards watching copying equipment. Well, in copy stores, they have human guards to check what you copy. But human guards to watch what you copy in your computer would be too expensive; human labor is too expensive. So they have robot guards. That's the purpose of the Digital Millennium Copyright Act. This software goes in your computer; it's the only way you can access certain data and it stops you from copying.
