I've been reading a lot about the topic: https://bitcoinmagazine.com/culture/the-impact-of-bitcoin-on-war is a good reference.

I think that it's always good to remind ourselves that the modern nation-state is more or less an invention focused on gathering warfighting populations with enough state-issued money to fund wars. Yes, there was an idea to extend this sort of thinking to government-sponsored bubbles in healthcare, education, and savings - but at its root, centralizing war innovation, war purchases, and war-fighting has always been at the root of the state.
