I mean is it not a good narrative to push? Someone in another comment pointed out each transaction uses so much energy it would be more effecient to just drive 600 miles in a tesla to hand deliver them money. That is awful, and basically for no reason, a digital currency could be designed without that entirely. There is no way to fix it, as proof of work demands that much energy be used no matter how effecient computers become.

An important nuance: such a bitcoin transaction is worth about a billion dollars. It's not a grocery store kind of transaction.

  That's also a separate issue, it _also_ requires trusted 3rd parties to broker small, everyday transactions, which has it's own costs (energy and otherwise) and fundamentally requires some centralization and/or escrow, which kind of defeats the purpose.
