Yes, sorry I don't respond as much as I'd like. I'm usually at work when I'm on.
That article on "IP" is pretty spot on. But there's also lots of political motivations. The law is made by lobbyists. And the holders of copyrights and patents have lots of well paid lobbyists.
To change something like copyright law would likely necessitate removing the lobbying in all of American politics. (Something that would be greatly beneficial as well.)
But since this is so wildly unlikely, I propose a different solution: Civil Disobedience. If we recruit the vast majority of citizens to believe that file sharing is moral and necessary (which it is) then this can take hold. Look at prohibition. It failed for no other reason than because it was a very very unpopular law. This is a PR campaign, and is already being fought.
Luckily, the MPAA and RIAA are helping us out by going out of their way to look like the bad guys! Their mere names are synonymous with corruption.
It's just a matter of time. It's a losing battle for them. File sharing cannot actually be stopped. There is no physical way to prevent it except to shut the entire internet down. And even then I could share files with people I know. Eventually the law will catch up.
