In view of the Dunbar thing I wonder what people here see as a eudaimonically optimal population density. 6 billion people on Mars, if you allow for like 2⁄3 oceans and wilderness, means a population density of 100 per square kilometer, which sounds really really high for a cookie-gatherer civilization. It means if you live in groups of 100 you can just about see the neighbors in all directions.
