Your 'what-ifs' are interesting ideas... but according to him, he didn't download the movie. So, unless you can prove otherwise, I think he has a pretty valid case. Stating that he owns the DVD doesn't serve as proof that he didn't download it, but it seems to eliminate the incentive, don't you agree? Anyone with enough money to fight the MPAA's lawyers has enough money, and probably enough sense, to buy the DVD instead of downloading it.
