It's one of those 'invisible hand' things where killing off older sharks may be advantageous in the long run. One of many possibilities.
One idea behind that is that any environment has a carrying capacity, limitations on food etc. It may be the parasites favour older sharks etc etc.
Would it be fucked up? Yes. But, that doesn't contradict a possible symbiotic relationship.
