Just out of curiousity I let Wolfram Alpha divide the total land area by the global population and got roughly 0.0191sqkm per person. That’s about a 130m distance if people were positioned on a grid. Then I found that roughly 57% of people live in cities. Treating the size of those as a negligible term that leaves us with roughly 210m. Then I found that 57% of land is considered uninhabitable which cancels out the city factor, so we are back to roughly 130m. I think this is a neat number as it really puts being kilometers or even tens or hundreds of kilometres away from others into perspective. The human density distribution on earth is really all over the place.
