It's an interesting question. How do people maintain control now? In general, it is not through physical control. We have institutions, we have "manufacturing consent".
We have those in a negative sense. Manufactured consent is mostly about directing motivation towards wars of control and acquisition and preventing other activities - including the peaceful development of sustainable energy, which is finally happening fifty years after it could have, and non-corporate non-military access to space on top of a non-corporate internet, neither of which are happening at all.
Manufacturing positive consent for a billion-year project is - obviously - a completely different kind of problem.
