You will not get a good society with communism either. Individual anarchism is the only society where the individual isn't oppressed
Not by the authorities, no, but by others. It is the theory of the strongest and the fittest, basically.
I don't see why anyone would oppress anyone more than in this system. In this system any psychopath who reaches a position of authority is almost
guaranteed of getting away with oppressing others. Other authorities support an authorithy abusing its power.
In an anarchy there is no hierarchy and no monopoly on violence. Everybody who wants has guns. Thus no-one can simply oppress anyone else. If some people try to create a hierarchy and a monopoly on violence, it will be easy to stop them, if everyone is determined to do so.
The paradox is that everyone who says that anarchism is impossible projects the worst traits of the state on the anarchistic system, although in an anarchistic system there will be no such traits, because an anarchistic system doesn't have the structure that allows those kinds of things to happen.
