Von neumann and bell pointed out that basically the non isomorphic fact that the spectrum $$\sigma(A+B)!=\sigma(A)+\sigma(B)$$ leads to contradictions.
If we but replace the sum by $$A\otimes 1+1\otimes B$$ then the above inequality becomes an equality.
This would make things much easier.
We would get as eigenvalues for chsh integer values for example.
