> Incentives are key to bring the technology back into the realm of usefulness (in the grand scheme of things). Externalities need to be priced into energy costs. In principle there is no problem with using the electric power of a small country for proof of work purposes, as long as the production of that energy is not harmful to everybody via global warming or pollution. I disagree. Pricing externalities into energy costs isn't sufficient, because proof of work is basically pissing massive amounts of irreplaceable energy resources into the wind in order to play a stupid, unnecessary game. I think it's better those resources stay in the ground or be used for a more productive purposes, and making miners pay more for energy isn't going to change the fundamental wastefulness of their activity.
