It's funny that you mention hubris and yet you fall victim to it by dismissing the measurement problem and Bell's theorem. It's true that our theories are not a perfect description of "true reality", but they do tell you something about what "true reality" must be.

> That Bell’s theorem “proves” something is language applicable to a mathematical structure, not to the physical world itself.

This is simply wrong, Bell's theorem definitely applies to the "physical world". A world that does not violate Bell's inequality would look vastly different to ours.
