Did Harry Potter's Secret Diary contain a EULA? I get into a contract with a publisher when I buy their wares? I have never had to sign a contract when purchasing a book AND I have never not signed (always requred to sign) a contract when renting a vehicle. Again, physical objects and intellectual property are not the same thing.
