You are paying more for the DVD because copyright law and fair use apply to it including the right to backup. Companies prefer to sell you new online licensing as a scam.

The US didn't correctly defend the right to backup, but that leaves a funny grey zone where WB being bad at making DVDs means less ability to shame "piracy" tool makers because backups is normalized and in no way suspicious if the media isn't perfect like they said.
