Bitcoin, the decentralised, mainly digital currency that is neither issued nor guaranteed by central banks, has always seemed like a magic trick. Rather than spinning straw into gold it transforms wasted computing power into money that people will actually accept as payment.
Radical libertarians have desperately wanted to believe in it because they hope it can resolve the following dilemma. They prefer markets to politics and they violently distrust states. But modern states in effect have a monopoly over the currencies that markets need in order to work.
Bitcoin, if it became broadly accepted, would challenge states’ dominance of the economy. It is designed to prevent monopoly by states or other entities, building a new currency based on shared information and making it hard for any entity to gain control. Politics disappears and a combination of technology and cryptographic proofs is conjured up in its place.
