Lots of real, normal markets are not reasonably well approximated by the rational choice model, and the elements of the model that are obviously literally false, and the degree to which reality deviates from them in the particular market, are pretty good starting points for understanding why that is the case.
"Normal markets" and "Econ 101 simplifications" aren't the same thing.
If you pay attention to the world around you, you see that time after time, better products win out over worse ones. It's practically common sense.
