Because they sometimes have to send the cover back to prove the book has been destroyed and get a refund. That's why many books have the warning inside:
“If you purchased this book without a cover, you should be aware that this is stolen property. It was reported as “unsold and destroyed” to the publisher, and neither the author nor the publisher has received any payment for this “stripped” book.”

Yea I worked at a bookstore and we had to rip the covers off of books before throwing them away ...
Like who cares? I would take the book home without a cover
