No you can't. Maybe that's the way it should be, but you certainly can't read that book to an audience or crack the DRM and print out copies for your friends.
I know, but I wrote "anything legal". Reading the book to an audience might not be legal, but running it through the reading software at my home certainly is not illegal.
You beg the question of whether it's legal or not. You claim it's legal because it's legal.
I totally agree that it should be, but I disagree that this has been established in any legal sense. Personally I think the evidence points in the direction of "it has never been considered legally".
