Now i'd like to see someone produce a cog that has -14 teeth or 0 teeth. Pretty lame attempt if you ask me. If you're going to pretend to be smart at least do it properly.
Nice try but you lose.
Just because a -14 tooth cog doesn't exist does not effect the validity of the proof. Since the set of real world situations is a subset of those for which the proof is valid it is fine.(If you really wanted to you could think of a negative gear ratio one in which the chain was crossed.)
