Elastic scattering doesn't effect the energy signal so we don't have to worry about it.

Fairy tales. Elastic scattering sure does affect the photon "gas" energy. Essentially, it's the same mechanism that works toward thermodynamical equilibrium in any gas mixture. Rarefaction can't extend the photons free path too far, just as I pointed out earlier.
