Hey you think they'll just fly over? PLANES CAN BE SHOT DOWN.
You think they'll just tunnel under? TUNNELS CAN BE FOUND AND FILLED.
You think they'll just climb over? LADDERS CAN BE PUSHED DOWN AND DESTROYED.
See? Because I can imagine ways in which things won't work, that makes it invalid. And don't even get me started on boats.
