> If bitcoin was changed to require a fraction the amount of electricity all of these ideas would suddenly fall apart
This is actually a weird game theory problem because there are a lot a miners with expensive hardware that would be worthless if such a change happened. You could fork it, but you'd have to attract miners after burning them (possible if commodity GPUs were viable, again), and you'd have to convince people that the new tokens are also valuable, and this isn't just Bitcoin Cash II.
Bitcoin has odd, long-term systemic risks based around miners.
