They have successfully made it illegal to distribute the software required to make such a copy. I.e., we have all been pre-emptively punished, as we are deprived of such a legal ability. Instead, we'd have to break the law just to acquire the software required to make such copies.
Obviously not.

The relevant cases have already been listed repeatedly in this thread. You are simply being argumentative here.
Nope
Not one case has been listed where a court has found against a person for making a copy for personal use.
The fact remains that the DMCA says what it says, and it says that bypassing copy protection to make a personal back-up is illegal.
And yet you have not a single court decision in 12 years of the DMCA to back that up.
What you do have is the world moving on, buying and using retail software for making backup copies for personal use.
