To be honest, it is one of the best books that makes case for Crypto specifically Bitcoin or its ilk from historic currency stand point. Let us not forget the President of United States has the right to mint a Trillion Dollar Coin, and some very intelligent people asked him to do that no too long ago (4 years ago?), when there was debt crisis looming in Washington.
The president of the USA can also legally fart in an elevator with CNN and MSNBC reporters in that elevator... But I would guess the president probably won't do that even if they are entitled to.
