"Every model is wrong, but some are useful." - George Box While every model is a simplification, and technically wrong. Some simplifications can be useful when they are right almost every time. But this is not the case here. This is too much of an oversimplification, he overgeneralized it. The only useful take away from here is "mind the long term consequences". Everything else needs to be decided case by case. "The costumer is always right" is an overgeneralization. It's not always right, it depends. It's not even almost always right. You'll need to be critical case by case more often then not. It's not useful to oversimplify this.
