If you try using an illegal scan of a print source, you'll be told that
you have no reason to believe the copy accurately represents the source.
I think David meant there's no rule that says there must be a
scan (legal or illegal) at all.
I think your point is that there's some precedent for rejecting
(or at least complaining about) sources that are only available
off-line.
