That seems to me like a natural argument against a natural hypothesis, rather than a proof that the hypothesis is supernatural. I guess I'm using a definition of "supernatural" like Richard Carrier's: "mental things [that] cannot be reduced to nonmental things" (http://richardcarrier.blogspot.com/2007/01/defining-supernatural.html http://richardcarrier.blogspot.com/2007/01/defining-supernat...). So under this definition wizards, psychics, ghosts and gods are all supernatural; but Bigfoot, UFO abductions and fairies aren't. The Artemis Fowl series is great. Although in the context of this discussion I find it funny that the fairies do have magical powers, it's just that flying isn't one of them.
