In some cases miners literally steal electricity or other resources to mine, so carbon pricing won't affect scenarios like that [1]. Maybe we can treat those as a rounding error... At the point where miners are willing to do things like build a transformer station you're in wild territory way beyond a neighbor tapping into your cable line for free TV. If the money's good, what's stopping a connected miner from bribing the right people to get a discount on electricity and skip the carbon tax?
