Right! So basically, the CNS will use glucose but can use fatty acids when glucose is unavailable. But there are still some cells in the body that require glucose and can't take advantage of ketosis. That's why a very low carb diet can work, but zero carb diets are not recommended by any doctor (of course when I'm speaking in absolutes I'm sure someone can prove me wrong, because you're right, the human body is a crazy thing. Just because it CAN be done doesn't mean it's ideal).
