Make no mistake, the U.S. has oligarchs too...

11. Oligarchs don't need nations the way that 99.9 percent of people do.

We need nations for a structured society and security, hopefully both are benevolent. Oligarchs can buy anything they need, effectively creating their own society and security forces often on large tracts of land or on islands (like Richard Branson's hideaway in the Bahamas).

An oligarch might prefer one nation over another due to the relative economic benefits and opportunities that facilitate his goals which may benevolent or not.

The bottom line is that oligarchs have little need for the citizens of any nation. A labor source or a standing army are probably the only things an oligarch finds citizens useful for.
