I agree that we should consider model uncertainty, including the possibility of unknown unknowns.
I think it’s rare that you can show that only one model is reasonable in practice, because the world is so complex. Mostly only really well-defined problems with known parts and finitely many known unknowns, like certain games, (biased) coin flipping, etc..
