It also doesn't use as much energy as the country of Iceland (living in Iceland here). You what we use the MOST electricity for here? Aluminum smelting. No one seems to care a lot about that waste, it seems.

Making aluminum isn't a waste! You can build airplanes out of aluminum. You can also relatively easily recycle aluminum into more aluminum things, so it's not like you have to pay that smelting cost every single time you want to purchase anything.

It's still subjective. We can argue all night about what does or doesn't deserve to have energy used on it, that doesn't change the fact that Bitcoin is a rounding error in terms of global warming.

If the purpose is to limit environmental impact, why are we choosing by subjective value instead of actual impact?
