That’s the “who pays for it?” political decision I was alluding to in my original post. Besides, today our economy is optimized around the assumption that pollution is free—as we learn to optimize around a carbon constraint, we will find some efficiencies here and there which will reduce the “cost” of sustainability (“cost” is in quotes because pollution is just cooking the books and it’s weird to characterize “not fraud” as a “cost”). Moreover, even if you’re of the persuasion that wealth redistribution doesn’t really work and the costs will still trickle down to the middle class, that’s still better than runaway warming.
