This post seems to me to be based on a mathematical error, namely the claim that energy is not local on momentum space.

The hamiltonian formalism is symmetric in position and momentum. Electrostatic potential energy is local on momentum space in a similar way to how kinetic or magnetic potential energy is local on position space.
