I thought it was pretty obvious. You said something on the cosmic level has to be important while one of the real definitions of cosmical is infinity or inconceivable, sort of meaning it could be anything that's in the universe.

"Here. Well, here as in this plane. Mundus. Tamriel. Nearby, relatively speaking. On the cosmological scale, it's all nearby."

This is a quote said by Septimus Signus, basically what I'm saying is that everything can be considered equal when you compare it to the universe itself which is infinite.

Plus Alduin's job isn't to destroy Mundus in fact it is just to kill the population and make way for new life, your taking his name "world eater" too literally.

"Those who overthrew him in ancient times only postponed the day of reckoning, they did not stop it. If the world is meant to end, so be it. Let it end and be reborn."

-Arngeir

Though Alduin's true intentions might be different from his main niche, I doubt that he has the power to destroy Mundus.
