Funnily enough, there wouldn't be any "depletion from the ground" in the substrate either. If the charge in the substrate was removed and sent to ground, the charges in the gate would also disappear and be sent to ground simultaneously. In that case, the circuit has lost its stored valu. Ideally, this should never happen, and if it does the circuit is literally broken.
