Georgist Land/Carbon taxes. Actually, looking over the earlier posts, I think I can see the half-a-point Bart R is grasping for.
IF land/carbon use is taxed, and the proceeds equally distributed amongst everyone, the effect is SIMILAR to what would happen if air was privatized.
The (huge) problem, as he half admits, is price levels. There is no way at all of mimicking proper supply and demand, and what will happen in practice is the level will simply reflect how much government wants to impose its energy-generation views onto its subjects.
And I do wonder how long the British Columbia politicians will resist the temptation to make the carbon tax revenue-positive ?
