Okay, maybe they wouldn't take down Youtube. But the chances of someone uploading a copyrighted video to Justin.tv? Or a thousand other small video hosting sites? Very high.

Right now, someone files a notice, and Justin.tv says "oh crap! Lets take that down." and they do and everyone is happy.

In the future, someone might file a notice, and then Justin Kan shows up at work one day and finds that his entire business has been taken offline by the government.
