Earlier quoted context omitted.
I think its hubris to believe that you can formulate the correct game theoretic model to make significant statements about what is and is not inevitable.
I don't think OP claimed that. There is no conflict between not able to formulate the true model vs the existence of that actual model. Just because we weren't able to discover all of the law of physics, doesn't mean they don't apply to us.
As a physicist I think people are more sure about what an electron is, for example, than they should be, given that there is no axiomatic formulation of quantum field theory that isn't trivial, but at least there we are in spitting distance of having something to talk about such that (in very limited situations, mind you) we can speak of the inevitable. But the OP rather casually suggested, implicitly, if not explicitly, that the submitted article was wrong because "game theory," which is both glib and just like technically not a conclusion one could reasonably come to with an honest appraisal of the limitations of these sorts of ways of thinking about the world.
