Like how treating magic like a mundane power source is inherently casting a light on the fantastical elements in said fantasy, and thus, just scientific fantasy due to a lack of fantastical elements. Or how the suspension of disbelief is a magic circle for narrative sense, and straining the suspension of disbelief, as per Samuel Taylor Coleridge, means that it could be broken; such as any of the Harry Potter "why didn't they X the problem away", because, magic is inherently a give and take on the individual reader.
