I'm not posting this as a disagreement to anything you've said, but if everyone on that list decided to drop carbs for protein/fat, there wouldn't be enough food for everyone. That's to say, before we can really cut out carbs from our diets we'll need to re-examine where our current food production is heading. The past half-century of advances seems to mostly have gone towards producing the most carbs per acre, albeit those carbs are typically then inefficiently converted into fat/protein (livestock). Soy is pretty good for mass protein production. Not sure if it would really be up to the task of what corn puts out in caloric density.
