This essay is pure defensive talisman. People use this hand waving to dismiss models with conclusions they don't like all the time. Yes, every engineering model makes simplifications about the universe, but so does every political policy. The responsible thing to do is to give models a proper analysis- what it solves, what it makes problematic, what it highlights and what it ignores. Yes, Engineers too often stop at the correctness of the model, and refuse to make moral or aesthetic judgements about the adequacy or appropriateness of it. That doesn't forgive the author's attempts to prevent scientific modelling of society.
