Stuff distribitors wrap their stuff up. Hackers create breaking technology to free it and there's nothing to be done to stop that. Stuff gets freed, even if its in the privacy of an individual's home.
Then another technology comes along (P2P) that allows the Stuff to be shared: it gets shared and there's nothing to be done to stop that. Stuff gets published anonymously from the individual's home into the homes of thousands of others.
So a law (DMCA) says, there's a (usually broken) technology to protect our Stuff, but you can't break it or allow others to break it. Too late, the stuff is out there, and will always continue to be out there.
Even if you add another law that says 'you can't share Stuff'. How do you stop people using Freenet to anonymously make Stuff public? That new law would be totally unenforcable.
So the next step of the corporate-backed lawmakers is to come up with a Better Law - even better than the appalling DMCA: the 'We own the Net: We own your Computer' law.
This law makes it mandatory on Operating System writers and vendors to include a reporting mechanism that can send back details on request of anyone's machine (what hardware, what software is running) to a central enforcement agency.
Further, it is mandatory on network owners to supply to this agency details of the ports and message protocols being used from anyone's machine.
If you're spotted running unapproved software or using unapproved ports or protocols, you are subject to investigation.
That's the only way to go! Look out for this law at a government near you.
