This implies the only content with moral worth are those that teach knowledge or skills, and presumably only the kinds that are worthy for productivity and advancement or something. But one person's "just an entertaining story or just a silly hobby" is another's life-changing or mind-opening allegory, or therapeutic pursuit with little immediate "practical" value.
