Why does Whole Foods sell things that are not whole foods?

Why do Grocery stores have an "Organic" section? Why is this section marked, or different, or special? Shouldn't  Organic be the standard? Shouldn't the NON-Organic sections be marked as different. Shouldn't the Non-Organic sections be marked, "Non-Organic". Shouldn't local be the standard?. Shouldn't Non-Local be marked as "Non Local"?
