Those restrictions are all just features of copyright law, not of a license. While the DRM associations have made outlandish claims at times, I'm not aware of any serious attempt to say that you don't own a copy of a movie when you buy it on Blu-ray or DVD. The DRM coupled with the DMCA's anticircumvention provisions combine to make it illegal to do things that would otherwise be fair use, but this isn't because of a license. One very important right you get by owning a copy is "first sale," that the copyright owner can't restrict you from transferring or selling the copy, and this is unaffected by the DRM. The store down the street that buys and sells CDs, DVDs, and Blu-rays is evidence of that. Even with the limitations of DRM, there's a very real difference between the kind of ownership you have with a disc and the lack of it that you have with pure-digital "buying" from most sources. (Though I believe there's some movement toward increasing consumers' rights to these kinds of digital "copies," in Europe at least.)
