Question

comparisons between cyberspace and terrestrial communities

Answer 1

While terrestrial governments are natural monopolies in their own territories, cyberspace governments compete. Terrestrial governments get overthrown when things get too bad; cyberspace governments simply lose citizens, much as a business loses customers. Former members may even go into competition with their old communities. The terrestrial government game is all-or-nothing (despite the possibility of loyal opposition), whereas Net governments an coexist. "Citizenship" is voluntary. A Net-based government can operate only by consent of the governed. Any Net government must therefore provide its citizens with real benefits if it wants them to stick around. Those benefits may not be just personal goods or services, but rather the broader benefits of a regulatory regime: a clean, transparent marketplace with defined rules and consequences, or a supervised community where children can trust the people they encounter or individuals' privacy is protected.

Notes:
Physical communities are an all or nothing game, they must maintain governing power, while cyber communities are purely consent of the governed, or people will vote with their mindshare.
