While I am also skeptical of the parent comment's quotes. The Euro is still backed by a centralized state(s) which does indeed have a monopoly on violence and require huge amounts of resources to maintain legitimacy. Crypto currencies demonstrably do not need these kind of resources. The rest of what people preach about crypto might be Bullshit, in a strict sense, but they are right about the anarchism thing.

All states by definition requires a monopoly on violence and resources to retain legitimacy. The currency is just a freeloader, and the consumption of resources to sustain a cryptocurrency is purely strictly additive.

The European Union has a huge standing army if they were counted as one force? Over 1 million active personnel. The US by comparison has 1.4m and China 2.0m
