Governments are inevitable. Even when you look at so-called "lawless places" or "failed states", you'll find governments: de-facto governments run by warlords and criminals.
Nature abhors a vacuum and that principle extends to power vacuums.

But there are plenty of ways (and plenty more each day) in which human and AI collaboration can fill power vacuums that don't require pseudo-sovereignty over huge landmasses or monopolies on the legitimate initiation of violence.
