I used similar reasoning. Much as I love my books, the Internet can give me most of the things I get from books - not as well or as satisfyingly, but it can still give me them. I would still be able to read fiction, and I would still be able to find out about non-fiction subjects. However, if I lost the Internet, books would never be able to replace the people aspect of the Internet - feedback on writing, email, LJ etc. I feel completely cut off from the world if I lose Internet access for a day, but I don't think I'd feel the same stress if I lost access to all my books for a day.
