Representative governments as consensus mechanisms, and how distributed ledgers enable competing governance service providers

Nation-state governments are a consensus mechanism, the main role is not governance, a government is used to form a consensus, using a monopoly on violence as a consensus mechanism that acts on lower level systems in the brain, the paleo-mammalian brain and the brain stem, as deterrents to enforce co-ordination around a specific state.

What distributed ledgers do is that they form a consensus without needing to use an ideology, as in, without being limited to one vision for how to be governed, so that there can be competing governance services.

The idea to vote for governments on the blockchain misses that blockchains use other consensus mechanisms than government, and hosting a "government" on top of them is, well, of course you can do that, but why, when there can be competing governance services?
