You usually have to make a large number of simplifications to create a Physics model too. The question is how those simplifications change the accuracy of the model.

We can generalize to more than just physics and economics... As the quote says, ALL models are wrong (no matter what field). If you have a model that is "right" then it isn't a model, is it?
