Annares is harsh, it even has earthquakes, perhaps to show anarchism in scarcity

Source: the dispossessed by ursula k leguin p. 141 Jeez, annares has to be barren but also gets frequent earthquakes. They chose hard mode for anarchists. They don't have post-scarcity, which is I suppose brave of Le Guin to remove that magical cop-out "missing ingredient" that we say prevents us from achieving it today.
