Pointing this out as a problem with the story's logic is like pointing out that a bear is much larger than a trout, and that it would have to eat multiple trout every day to survive. This is not a reason for a bear not to eat a trout, it is a reason for a bear to eat a lot of trout.
But if the bear has to use several billion times the energy it gets from eating the trout to catch every trout, that's a reason.
