Lets instead view the idea of book-only media.
Lets pretend Wikipedia was converted to paper encyclopedia:
What kind of overhead would occur for correcting a single article? How many books Wikipedia will have to print to spread its data, and how much it would cost to replace internet wiki pages with mail delivery of wikipedia books?
How much trees would be required to supply 100M readers with copies of wikipedia?
Of course such blatant waste of resources would be absurd, yet you can see the entire book industry as just that..and continue buying books.
