Yes, there is some spatial optimization needed insofar as one would likely not want to be two acres in linear distance away from one’s infant. The habitable surface allocation could be thought of as virtual and fractional which would also account for point differences in relative value such as a natural spring, naturally occurring commodities like a gold mine or the human interest in subjective value like Hawaiian beachfront, all of which may change over time. Along the line of subjective preference is overall inter-human proximity in which some might choose higher or lower depending on intended lifestyle.

Human-avoiding life already has a hard time. The habitable surface estimate did not include many areas where the remaining ones exist, such as tundra, ice pack, mountains and deserts. Additionally inter-human proximity preference distribution will allow for additional area outside the aforementioned surface classifications.
