Oooohhhhh - the laywers would love this, wouldn't they? If I see an ad for a book, should I expect the book to come with five paragraphs of "fine print" that explains "You aren't actually buying the rights to the book, you are just buying a copy of the book. You can't print your own copies, you can't blah blah blah." I know that books themselves have it but do you want every ad to have this as well? Silly.
