I completely agree. Every model is "wrong" to some degree, it's just a matter of applying the "least wrong" one in the proper context to yield the most practicable solution. Even basic circuit theory (Kirchhoff's laws) falls apart when the preponderance of propagating wavelengths become close to the characteristic length of the propagating medium. Then that "wrong" simplifying model must transition to the much more complex transmission line theory. By the same analogy, one doesn't use basic Bernoulli pressure/velocity/flow equations for plumbing when dealing with chaordic or turbulent flows outside of very limited Reynolds number regimes--one has to do numeric simulations of the more general Naiver-Stokes vector differential equations.
