"It's the map and not the territory," right?

I may be way off base here, but isn't the root of this disagreement that lukeprog is saying that our mental map called "conceptual analysis" doesn't perfectly reflect the territory of the real world and should therefore not be the official model. While Morendil is saying, "but it's good enough in most cases to get through most practical situations." Which lukeprog agrees with.

Is that right?
