It's a way to keep other players honest.

In a game where your career, or your life, could be over in a matter of seconds over a single hit, the idea that you could get your teeth knocked out by someone for it is at least a slight deterrent.

When the fines amount to little more than pennies and suspensions rarely go beyond a handful of games, having to answer the bell for your actions can help keep a player honest.

And people may rarely get injured fighting, but try and tell me someone 6' weighing 200lbs punching you full in the face isn't going to hurt.
