Whilst I appreciate your point, I'm not sure the analogy works. Your 'book' (website) is being deployed from your warehouse (web server) and you could chose to not deliver to the customer (the client web browser) based on their location, because of local (to the customer) laws that ban the book.
I think it'd be difficult to argue against that unless someone else was a proxy middleman during the delivery of the book (VPN).
