No. I'm saying that the flaw lies deeper than the models, flawed as they may be. Economists PREFER flawed models because the flaws enable them to make claims they couldn't make with "better" models. For the same reason, they will either reject any "new paradigm" or they will corrupt it to serve the professional purpose of justifying inequities and rationalizing unreason.
