If I estimate a model to predict an anomaly using data that never has any realized anomalies, how well will that model do out-of-sample? While framing this as a bad unrestricted ROE maximization problem is a nice simplification, it's not clear that having everyone move to a restricted ROE maximization subject to keeping assets large enough to insure against some unforecastable shock is welfare enhancing. That could be a lot of wasted insurance.

I will give him credit for cleverly spinning this logic all into a pitch to kill the unrealized cap gains tax proposal!
