I disagree with any law that tells someone what they must do with their intellectual property. As much as I enjoyed the 1985 pro wrestling comedy "Body Slam" I don't presume that the owners of that piece of entertainment are obligated to preserve it or present it to me in any high quality format, if at all.
However, I think a rule that packaging must honestly proclaim what is in it, both in food and DVDs is a fair rule, especially in the case of "Star Wars" where LFL has intentionally created so much public confusion.
