I think this reading did a great job of breaking down some of the issues of how our culture is being shaped by the Internet and the systems it has created. Lessig argues that we are experiencing a major shift in property and culture, and that our culture is more "owned" now than we ever would've let it be prior to these modern Internet-fueled changed.
I liked the connections drawn to the Causby and RCA cases. Though both are extreme examples, I do think they serve to frame current the current "piracy" discourse in a way I haven't really though about it before. Lessig emphasizes the importance of common sense and updating our common-law based system of laws to match what makes sense today, a concept that can change rapidly if technology does. It seems to me that people like the MPAA heads mentioned in this article tend to latch onto letter-of-the-law interpretations. And frequently, that means going against what is really the appropriate policy for our times and larger national tradition of culture.
