Anarchism as a political philosophy strives for non-hierarchical cooperation. It's hard to say what an "end-stage" anarchist society would look like - anarchism focuses more on how people should go about organizing than the results of the organization.

I tend to imagine society organized across geographies by trade and industrial unions and in localities by consensus-driven democracy with local councils handling the day to day administrative tasks. The economy would primarily function almost as a gift economy, possibly with some markets for luxury goods.
