I think you're coming from it at a different angle here.
The basis of the story is still: The hero defeats the badness and claims their price.
It doesn't matter to the basis of the story who the hero is, or what the badness is or what the price is, it's still about the hero's struggle against the badness and then they get a reward in the end.
By changing up the hero, the badness, and the price you can get vastly different stories. Let's say it's about a dragon who's going to rescue her knight from an evil princess. That's a very different story from the knight rescuing the princess from the dragon, but basic idea is still the same.
And if you boil down all the stories in the world to their basic parts you'd only have a handful of different kinds of stories. It's by changing the details that new stories are possible. So what's your point?
