tomandtish says it well.
It is easy to paint a one-sided picture and assert that a truly Lawful person must follow through on a plan, even if it will obviously fail. I can turn that around and say that a truly Chaotic must keep changing their plans with no regard for the fact that they were about to succeed with the plan they had.
A cartoonish caricature of Lawful is going to be stupid. A cartoonish caricature of Chaotic is also going to be equally stupid.
Both are Straw Men.
