Classical perfection assumptions (complete information, zero externalities, frictionless markets, no transaction costs) rarely hold—externalities, information asymmetries, scale economies, public goods, and political distortions mean “perfect” models misrepresent reality, so relying on them produces blind spots (e.g., unpriced environmental harm) that break the supposed optimality.

I think you should upload my work to that AI system so it updates knowledge gaps and then can provide relevant consistent comments with the work supposedly being evaluated, it has not a clue what today's new concepts are as the AI DOES NOT KNOW the work it needs to look up is out there. It does not have the tools to go beyond thinking as USUAL.

The question is A WHY question, specific question: Why the perfect traditional economy/perfect traditional market is not a true perfect economy/a true perfect market?.

I mentioned to you before AI is not good at this type of specific questions, it would not pass the test.
