I believe in property, especially intellectual property. And I agree this is a contentious issue. But I also believe that this debate is not a simply dichotomy between those believing in property rights and "pirates" who do not.

I'd propose checking out the work of Stanford law professor Lawrence Lessig, who has written eloquently on this issue in several books and is the founder of Creative Commons, an organization (and concept) that offers a particularly compelling "alternative" to a simplistic understanding of intellectual property rights in the digital age.

Check out his site: Lessig.org

And take a look at his publications, especially Free Culture (2004) and Remix (2008).

Worthwhile reading on this subject.
