I quite agree with Lucalibur; Steel, Dragon and Ghost acutally do make sense compared to Sound, Artificial, Void and others like that. Granted none of them are true elements (A substance made up of one kind of atom.) But this game is also meant to be a children's game. (At least the Story and Catch'em all portions)
In argument to the Light-type, It could exist but it partially exists in the Fighting-type. Plus, How would this type be balanced?
