"We are going to offer all the services the state offers now but only better" is the silliest argument ever. You run into the exactly same resource and distribution problems as the government has, and you are going to start instituting the same sort of structures sooner or later.
Hierarchical systems are not enforced on people by malificient power hungry lords. Humans self organize into hierarchical system. If you are planning this "total-decentralization" you better have a plan on how to negate this natural "follow-the-leader" instinct most people have.
The second is the historical example. The only time anarchists come to power is in time of great trouble. Mainly because the dominant political force has fallen, and everything is in chaos. Another political force has risen sooner or later, only to install hierarchical power structures. With great misery to most involved.
Doing anonymous good deeds is one thing.
Speaking of a revolution is another.
