No Copyright For DRM'd Works

A commenter on Slashdot just made the most interesting argument. He argues that copyright is granted with the expectation that the work will eventually enter the public domain. Accordingly, he argues, works that can't enter the public domain because of Digital Rights Management restrictions shouldn't be granted copyright protections.

I think the key concept in intellectual property laws should be that the creations *must* enter public domain at some time, and remain in the public domain [forever] after that. Therefore, the law should provide no protection at all to anything that's protected by anything other than the law itself, or for that which isn't fully disclosed.

No copyrights for anything distributed with any sort of DRM, no copyrights for anything distributed under proprietary standards, no protection for any software distributed without source code.

I think this view is a bit extreme, but it certainly raises a valid concern about DRM.
