When I was in Anadarko they were capping many wells as soon as they were established because of fear of a glut and no pipelines to refineries, trucking was too expensive, refineries were way off in Borger, TX. Many are still capped.
No, I'm not in favor of such "absolute" type legislation as a ban. I would prefer tariffs on imports, perhaps based upon a gradual increasing amount to discourage it but not leave us in a bind during an upset condition.
