> You're equating the existence of copyright as a principle/law and the existence of DRM as a technological means of enforcement. They are not the same thing at all.

I'm not comparing copyright and DRM. I'm saying DRM is a consequence of copyright.

As you noted, technology is the only way rightsholders can effectively protect their property. Since the copyright industry is worth many billions of dollars, they have more than enough money and influence to make their DRM technology a reality. The computer industry is going to back them up. The result will be computers that obey them, not us. Computers that only run the software that they approve, software that does their bidding.

The source of this evil is copyright. There should be no imaginary property to protect in the first place.
