Brains can create value to society. Brains can create shleter, science, Gods. We, Humans, have evolved to become what we are because we have bigger and better brains than all other animals. Not because we were the cutest apes. Beauty is subjective and relative.
What kind of value a beautiful body can bring to society just by being beautiful?
Seriously? I think the answer is self evident.
Beauty is not subjective and relative. We are hard wired to appreciate beauty (proportion) from the earliest ages. Study after study has confirmed this.
So culture has no effect on how we perceive beauty? Anyway...this has nothing to do with the original argument.
