Proof that quantum mechanics is internally inconsistent on antihydrogen

Quantum mechanics (QM) theoretically forbids natural H-antiH interactions because of annihilation in the Dirac sense. But in practice, ab initio QM relies explicitly on HantiH attraction, which it theoretically forbids, to arrive at attractive forces in the molecular hydrogen cation, given away by the cusp in its PEC (potential energy curve) at exactly 1,06 Angstrom. This internal inconsistency in QM is easily removed by lifting its irrational ban on natural antihydrogen.
