The objection to this is something that could be an interpretation of the original post: the Wizard of Oz can give fake brains to the Scarecrow because his problem isn’t really a lack of brains. But “his problem isn’t really what he says it is” is a situational thing that isn’t true for everyone, just like “writing Chinese characters is relaxing” or “sleeping outside is good for you” aren’t true for everyone, so you should be cautious generalizing it.
