There is an excellent article on why we need better copyright legislation than currently exists, and by that I don't mean "more restrictive": http://www.darknet.com/2005/06/story_the_tech_.html

In the above-linked article, the CEO of Intel explains that someday soon we're going to have video recorders at home that we'll want to use to stream TV programs to our car, boat, or vacation spot.  We'll want to do all kinds of fun and interesting things with the content we have.  But if the current DMCA laws stay in place, or we get tougher than that, we're going to lose a lot of good creative outlets.

It's a great read.
