To me this is preferable to putting it in a large cardboard box with bubble wrap like they seem to do for even tiny but durable products like finger nail clippers. It’s much less of a waste and I don’t mind if a book is slightly creased.
Powell's (for example) have a good alternative, they stack several books on a piece of cardboard the size of the box's bottom, then shrink-wrap the books to the cardboard. The books can't slide around, and can't move much. I've never had any arrive damaged (unlike AMZN).
The energy used by re-shipping damaged goods must outweight cardboard waste?
