... No, I think you don't agree with him - or if you do, you're conflicted on the issue, and you're laboring under at least one false apprehension.
Here's the thing: if one truly believes in a system of justice and the rule of law, then one must refuse to recognize the validity of any contract that is not of equitable nature (be it equally fair or equally unfair).
So if you truly agree that copyright is no longer equitable, then (given the above) you must agree that _neither_ party is required to abide by its terms as-is. You don't get to call it theft, because in the absence of copyright the information that comprises a work _is neither tangible nor property_: stealing a "Harry Potter" DVD does not steal the concept of "Harry Potter" itself.
This is why I generally consider any attempt to "copy-protect" a work, via a method that does not allow for the "limited times" clause of copyright law, to be either an act of fraud or a disavowal of the creator's rights to protection of that work under copyright law - because to deliberately attempt to make your work un-copyable while claiming the protections of copyright law would be tortious misconduct.
Which doesn't mean I go around copying DRM'd movies on principle - there's more than enough free/cheap legal media for me to spend the rest of my life watching if I wanted to be a couch hermit - it just means that I recognize contracts (are supposed to) go both ways.
