No, we're just telling you your moral intuition is absurd.

People are very desperate to try to claim that something that's highly nuanced is actually obviously morally wrong, because it makes them feel self-satisfied.

I would disagree on the "obviously morally wrong". What's the alternative for the books if they were "saved" from the fate of being scanned and shredded? How many rare books have you personally brought in the last year? Not everything that's ever created needs to be preserved forever.
