I would consider cypher punk crypto anarchy the first left libertarian form of governance (edit: that could function on a global scale), an interesting hybrid of communism and capitalism.

Communism today is incompatible with democracy, it needs authoritarianism to have the level of control needed to redistribute all resources.

Right authoritarianism creates social hierarchies

Right libertarianism tries to be decentralized but just recreates feudalism

Left libertarianism is typically impractical. If the government doesn't have authority to tax, how can you redistribute wealth? If the government doesn't have weapons, how can it tax? If the social organization is decentralized, how do you maintain cohesion? If anarchy is rules without rules, how do you create rules without rulers?

Blockchain solves some of these problems. Maintaining an identity system is the main hurdle. In a crypto currency like Bitcoin, your private keys which prove ownership of money is your identity. But if it was just your computer was your identity, people could just spin up multiple computers and vote 10 times.

So unfortunately, the "rules of governance" are limited to network rules about the Blockchain. If you can implement a decentralized ID, you can securely automate parts of the government that have to do with things like voting or proposing policy.

Anarchists are by definition not conservative
