You're again looking at government systems as personal choices, and not as intrinsically tied to the economy. Just because you can imagine a form of society doesn't mean it's actually feasible in the real world, this is called utopianism, ie crafting a utopia in your head like someone picking out their outfit for the day, rather than through economic analysis.

Further, most anarchists would consider themselves communists, though the focus on horizontalism makes it a very different form of communism from Marxist communism, which is fully centralized. Moreover, "totalitarian" isn't a form of government, really, just a descriptor for levels of freedom of an individual in a subjective, negative manner.
