We know that the canonical position-momentum commutator relation is fundamental in quantum mechanics, but would it be possible to derive it starting from a different set of first principles, more specifically starting (in Dirac notation) from
Closure relations $ \int|x\rangle \, \langle x| dx $ (both momentum and position bases).
Orthonormality$ \left\langle \left.x'\right|x\right\rangle = \delta \left(x-x'\right) $ Orthonormality relations for both bases.
The$ \left\langle \left.x\right|p\right\rangle = e^{\text{ipx}} $ the assumption that momentum eigenstates are plane waves in the position representation?
