No, how about many people act together voluntarily in a distributed system of social support that is resilient to attack by small numbers of powerful people?
Because people need to pool into something to be able to afford big projects for the benefit of all. Government is the effect of this, you collect taxes so you can afford to build a shiny new hospital to attend to a region.
If you want to pool resources collectively in a smaller scale you are just replicating this structure with different powerful people, or different structure of power, but a society will always need it, doesn't matter if resources are money, materials or labour.
