> Which is why Bitcoin mining is only feasible in the areas that have the lowest electricity rate?

Nope, not where Electricity is cheapest, but where it's opportunity cost is lowest. In developed nations with a stable currency this might be high, in others that don't have the privilege of printing the world's reserve to bail out bad decisions, different story. And that's what the market is reflecting.

>My understanding is that a substantial fraction of that inefficiency is things like "there's power loss in running power from a power plant 100s of miles away" or "converting from AC to DC power induces power loss

Precisely, most Bitcoin mines are remotely located right next to the power plants, partially for this reason.

> There's no need to invent new demand to manage existing demand.

No you need demand to bring excess supply.
