While I agree that the punishment is often too light (or non-existent) for drivers who endanger cyclists, I believe that the punishment in this case is deserved.

There are several issues here, including endangering others who belong on the trail, endangering rescue personnel, and destroying sensitive areas that the National Park Service is trying to protect. Perhaps the 5 year ban is over the top, but I believe the $500 fine is too low.
