Any community sourced organization is a governance organization, pooling capital in a way that is agreed to by all, and distributing that capital in a way that is agreed to by all. Whether we call that a "government" is honestly a distraction.

The State is a form of governance I reject on principle. I have nothing against entering contractual forms of governance voluntarily.
The wording may seem a distraction to you, but the fact remains that what most understand as government is whoever has control over the State at a given point, and the State is fundamentally coercive.
So if a town decided to use tax dollars to buy a bitcoin miner and distribute some of the bitcoin generated to all citizens of the town, would you consider that to be self-organizing and voluntary, or centralized government control?
