Points per game shows how good a defense is at stopping their opponents from scoring. It also doesn't need to be adjusted for quality of opponent either. If your defense knows how to keep an offense from scoring and is actually good at it, then nobody will score a lot of points against you, no matter how good or bad they are.
I think that's a pretty outdated way of looking at the sport, just like looking at Wins and ERA as the primary way of evaluating a pitcher is a pretty outdated.
Points is just so context dependent. If a team holds another without a first down all game, but the offense fumbles inside their own 10 yard line and then the defense gives up a score, should they really be penalized? A defense that plays against BYU or Texas Tech might face 25 more plays than they would if they were playing Arkansas. Should they be penalized? What about field position?
The variance between style of play, and quality of players, is so vast in college football, that data like total yards, points, etc is just really limited. We have the tools to give us more context, and efficiency statistics are, right now, the best way to do that. They aren't perfect, but they tell us so much more than just "who scored?". Since stopping somebody from scoring is very complicated and relies on a bunch of different variables itself.
