I agree, but at the end of the day every human being has the power of coercion through violence. There will always be individuals who will seek to do violence, to break the “laws” in whatever form your collective makes them: assault, murder, rape. There must be power to coerce violent individuals away from violence.

Whatever organization you devise, run a thought experiment to test it: imagine a clever, charismatic, amoral sociopath, hungry for power and willing to do anything to achieve it. If no position of power exists to seize, they will create one for themselves. They’ll blackmail people, threaten them, even kill them. They’ll surround themselves with thugs to assault and threaten people. They’ll create a criminal empire. How does your system prevent such tyrants?

It’s not enough to have a government which itself isn’t oppressive, it must be able to prevent ambitious sociopaths from becoming oppressors. Otherwise you’re just in a lull between tyrants. Violence can never be eliminated, ultimately it must be restrained by the threatening presence of superior violence. Ideally the presence alone is sufficient deterrent, but without any deterrent you’re constantly at risk of ambitious sociopaths
