It would still be unfair for original manufacturers of DVDs..

Well anyway I would still rip dvds instead of buying, lol :)

How exactly did you arrive at this conclusion? As a matter of fact: Billington announced six cases where copy protection circumvention is not copyright infringement. And only 1 concerns protected DVDs.
“Motion pictures on DVDs that are lawfully made and acquired and that are protected by the Content Scrambling System when circumvention is accomplished solely in order to accomplish the incorporation of short portions of motion pictures into new works for the purpose of criticism or comment, and where the person engaging in circumvention believes and has reasonable grounds for believing that circumvention is necessary to fulfill the purpose of the use in the following instances:

Educational uses by college and university professors and by college and university film and media studies students;

Documentary filmmaking;

Noncommercial videos”

Nowhere in the 262 page document does it condone making a backup copy of a protected DVD.

Specifically it states: It is important to add, however, that no proponent has demonstrated the need to circumvent in order
to copy a motion picture in its entirety, and no proponent has demonstrated the need to use a quantitatively large percentage of a motion picture. The motion picture industry has a legitimate interest in preventing motion pictures from being copied in their entirety or in a manner that
would adversely affect the market for or value of these works, including reasonable derivative markets.”

And also: As noted above in the discussion of the third fair use factor, the examples presented in the record consist of uses of short portions; the record does not support designation of a class that would extend to anything beyond
use of short portions.

And: While the Register continues to believe that a class of, for example, “motion pictures for non-infringing purposes” or “fair uses of motion pictures” would not constitute an
appropriate class, the relationship between the “class of works” and the particular non-infringing uses that were proven to be, or likely to be, adversely affected may be, in certain cases, the optimal means of balancing the interests identified in the record.

Please actually read the document you are referring to when arriving at a conclusion. The conclusion you have drawn about being able to make a backup copy just makes you look silly.
