You are not missing anything. In fact, it is those who are purchasing organic foods that are missing something. They are missing $$$ from their wallet!--not to mention harming the environment. The supermarkets love it however. The make about 4 times the profit from organic foods. How would you like to make 4 times as much money from doing the exact same amount of work? Now you see why the big fuss? It's called marketing.
I was listening to an expert on this subject on the radio talking about the myths of organic foods. One thing he commented on was that plants produce natural pesticides to ward off pest insects. When measured with modern detection equipment, these natural pesticides are thousands of times stronger (measured in parts per billion and parts per trillion) than the man made pesticides residues on foods, even if you don't wash them at all!--due to our strict regulations regarding pesticide use, their biodegradability, etc! When you add to that, the fact that the more vegetables you eat the longer you live, better you resist disease, etc. as shown in actuarial tables, it is clear that the benefits from eating large amounts of vegetables outweighs any negative effects from pesticides-natural or man made. --And studies have shown that natural vs. synthetic pesticides produce the same side effects at similar doses. Natural isn't any safer.
And how does organic hurt the environment over non-organic? More land needs to be cleared for farmland because of the lost product from pests, and more land needs to be used due to smaller crops due to the use of less efficient organic fertilizers, and more land needs to be used just to make the organic fertilizers in the first place.
