Even if you have the total information at every state, what does it really tell someone who wants 'information about New York City?' Without smuggling in top level correlations, we can't answer even simple questions like 'What's a nice place to eat?' or 'are New Yorkers rude?' To me, it is clearly the 'levels' which are more primordial and more informative than the theoretic invariances across the levels.
