And neither is highlighting bitcoin, especially by focusing ONLY on the mining aspect of it. The use of the network is also part of the bitcoin story. If instead of using new bitcoins mined they did transaction value per day (ie, $20B+) the math would be totally different.
If you applied this same damage model to something people had fondness for (ie, driving an electric car) you'd realize we should be working as HARD as we can to kill EV cars dead, because there is a MASSIVE unaccounted for cost to charging them (using this model).
Reality though is bitcoin chases low cost power, and that is currently often actually green (hydro, excess solar during day when their is curtailment and negative pricing etc). I can't imagine the economics making sense to mine using coal power.
