Geometry and Tyranny
The Hebrew word for Egypt “Mitzraim” means “narrow land,” no doubt because the populated parts of Egypt are limited to a narrow strip of land near the Nile. Could this have produced its totalitarian government? In Egypt, it was possible to set up a few watchposts that could keep potential rebels from going from place to place unobserved. This is more difficult in a two-dimensional system.
What would be the effects of going from two to three dimensions? For example, on the ground, two competing transportation systems will run into each other and might need government regulations. In a space colony, there's no need for two competing transportation systems to run into each other at all.
