I think all wildlife consider energy tradeoff, which is why, say, a lion will expend more energy chasing a zebra than a rabbit.
As to bass, I don't know how far away they can detect a lure, but we can't really compare their chasing a lure to a terrestrial mammal. At what distance does energy expenditure become a factor for bass? I have no idea, but I doubt that it's much of a factor for short distances. So I do think they'll take small lures.
Also, it is believed that bass strike lures for many reasons, such as anger, curiosity, territoriality and others and I don't know if energy comes into play when striking lures for these reasons. Lots of mysteries beneath the surface. But I'd try all sizes of lures if you're not getting the results you think you should.
