In my opinion, it's a better return than calculating SHA hashes with no aim other than to do work.

We could prioritize computing problems by increasing the reward for working "more important" problems (find asteroids that are going to hit us?).

It's better but not much better. How do you avoid an arms race? Who gets to decide what problems are important?
