Yes. Nationstates very much want to make the proven distributed mechanisms of consensus that allows people to exchange value without their oversite illegal. No significant cryptocurrency has gone proof of stake, and certainly none just starting out. Etherium will never actually switch. Making proof of work illegal would make effective cryptocurrency illegal.

The violent standing armies (and their logistics networks) that protect other international currencies from manipulation and attack use far more energy and do it in very violent, centralized ways.
