Using your logic you can't use a 22-250 Rem instead of a 223 Rem since you can shoot farther and faster. Oh wait, why would you be able to use a centerfire at all? Better use a rimfire since it is more challenging. Oh, scratch that, you have to use a rock and throw it because all firearms are unethical and shouldn't be used. Can't wear camo either since that gives you an advantage. For that matter you can't wear clothes at all since we were all born without them. Oh, and you can't use your cognitive reasoning since it would be unethical to gain an advantage over the animal....Geez.
