Your selection arguments make sense to me. We are conscious, so consciousness must increase fitness. Maybe impulse control is a key aspect of it. And thinking of Hofstadter, maybe it's just the top of the self-referential stack.

Impulse control could be part of it, but it's not clear that that requires consciousness, either :)

We know that perceptual awareness has some connection to biology (sleep, seizures, drugs, etc), so to the extent that consciousness requires energy, it has to justify its caloric expenditure.
