Better, the government agency could be removing the reason that the cost can be externalized in the first place. Admittedly, this is difficult to do for resource extraction or pollution costs. But consider that we can recover the costs of pollution in the ground and (to a lesser extent) the water. The reason we can't internalize the cost of CO2 emissions is because we won't recognize any ownership interest in the air. I'm not sure how to do that either, but I'm hopeful that we could think of something if we'd at least acknowledge this.
