I have to say this is not a very well thought out argument. Plus the kinds of arguments he makes about hierarchy, control and the state are extremely authoritarian. It seems to boil down to, we can't enforce a galaxy wide police state, so let's stay here on Earth where we can really keep people under control. There might be lots of reasons not to colonize space but that's not one of them. Also, if it takes decades or centuries and a huge amount of resources to even travel from one system to another, what reason could there possibly be to send an invasion fleet? The idea is ludicrous. If you can't meaningfully control some other system, doesn't that remove the justification to go to war?
