I'm deeply sympathetic to this viewpoint, and definitely oppose book bans and restrictions. That being said, I think you're misinterpreting OP's perspective. They aren't (at least not deliberately) proposing these restrictions out as some punishment for immorality, they're specifically concerned about safety. If significant numbers of people die that wouldn't die if books were restricted, that's at least an argument for a ban.

Again, I'm not saying at anything near enough people die due to book-organized hits to swing the scales. That seems...unlikely, to say the least. I'd just argue that there's a difference between keeping all the kids in at recess and hits being called.
