So the hitch will transfer the impact to the frame?
What's the bumper attached to?
A hitch can also act as a lever, amplifying the force of the impact and converting that to a torsional stress on the frame. Bumpers do not have this ability, and are literally designed to absorb a portion of the impact before transmitting it to the frame. So even though a hitch might reduce the damage to the back of your vehicle, it will have other undesired consequences. It's not just about damage to the vehicle, but more so about injury to the occupants. A rigid connection between the impact site and the frame of the vehicle means there is a much greater whiplash effect, which is the exact thing car manufacturers are trying to mitigate with bumpers, airbags, etc.
