I agree. How much waste do fiat currencies generate protecting their themselves with standing armies (or the alliances with a country that has one)? Far more than the amount of energy used to secure bitcoin currency against other nation states using proof of work.
Iregardless of what ones opinion on maintaining standing armies might be usually it creates significant added value (unlike mining bitcoin) for the economy. All those people in the military or working in industries producing for the military have to be paid etc.
