Inane,
The answer to all your questions is an obvious no. Movie rental stores exist legally, and they even make a profit from lending out movies.
A more interesting question would be: could you be held liable for allowing a friend to borrow a hard drive containing all your own legally ripped MP3s, knowing full well that they could easily copy the entire contents before returning it into your possession? Could you be held liable for letting him/her borrow all your original media knowing the same?
The Induce Act is some pretty scary proposed legislation.
