alt Hacker News>But that's not a reason to blanket-discourage expression
nor was there a reason to blanket discourage treating books as precious and worth preserving. i'm interested in the part where you note what you noted and let the other glaring transgression pass. That was a choice.
Knowledge is precious and worth preserving, sure, but a specific copy of a book? Unless they're doodling in the margins of historical documents or rare manuscripts, I personally can't see any reason why it should matter.
