Technology is inseparable from social forces and pressures. You can't talk about the internet apart from the people who use it. Bittorrent is not the threat, but the people who use it and the reasons they do so. Those people and their reasons are not going away IF the only thing that changes is more people being sued. The only thing that might go away is Bittorrent. If all file sharing services were forever shut down tomorrow (and they really can't be) then file sharing would only get more difficult, not impossible. If you want to stop file sharing, you need to figure out who those people are and why they do what they do, then give them a better option.
