All these services don't need a hierarchical state.
You think people will just build roads out of the goodness of their hearts? Or pick up trash? Obviously not. Those services have to be performed by somebody who is getting paid, and in order to pay them, you need to levy taxes. Boom, hierarchical state. The rest is just details.
Like it or not, the world is too big and complicated for everyone to live in self-governing communities anymore. Like imagine applying what you're suggesting to a densely packed population centre like New York. It makes no sense.
