There is no central authority of humanity, just deeply embedded factions with long histories. If you don't think the same is happening to Bitcoin just look who the biggest players are in crypto (hint: it isn't decentralized individuals.) Bitcoin offers nothing new from the perspective of game theory, and only seeks to offload consensus to software which fails against hard power anyway.
Over three millennia ago, humans had the Bronze Age, which included two global markets (copper and tin) and had international trade without any central authority setting the prices.
