Politics happen due to people. There is this myth that you don't need management or leadership at all. But there are enough examples of bad managed teams and bad self directed teams that its pretty obvious that politics happen in the absence of management.
If you had a superintelligence it could basically manipulate people so even if you don't connect it to the internet it could try to further its goal. There is also a chance that their goals are not the same as ours.
So we need a way to discern intent from AGI and higher and the ability to align the goals.
With that said I'm not sure if we ever get to them being self driven and having goals.
