Without wishing to get too sidetracked on this one, I think this is a fundamentally different debate.
There is a difference between suggesting that a certain industry may have seen it's hayday and suggesting a fundamental top down restructure of much of society.
It confuses me in debates like this because you have one set of people wanting to create new startups to displace hollywood and another wanting to kill IP altogether and they seem to act like they agree with eachother.
The problem with this conversation is it always gets confused between "The MPAA are evil, let's kill them" and "let's abolish copyright!"
The only way I can see to kill "big content" would be to either reduce the size of the overall industry, or to break it up into smaller indie houses.
Neither of these seem plausible.
