I think everybody in the world could get a one acre plot in Alaska, and have room left over.
Unfortunately, after 24 hours, they'd kill each other and turn cannibal...Those standing on their acre in the high elevations, would quickly freeze, roads would be solid gridlock etc etc.
It's nice to make analogies like that, but it's really pie in the sky.
Ya see, there are many regions on this planet, that are all but uninhabitable, and not able to sustain an economy, major populations etc etc.
It's just the way it is.
