In order to first learning how to add, examples with apples and bananas are helpful. Learning happens by relating some new concepts to something you already know; that applies also to monads.

Those monad metaphors provide the same benefit. Even if some intuitions are wrong and you still need to learn the match to get the whole picture, at least you get a sense of (partial) understanding and purpose during the whole learning process thanks to the metaphor, instead of feeling lost the whole time.
