Do you see the kind of hegemony certain states hold over the world? Many nations can't even self-determine their own states without a superpower knocking off leaders or supporting rebels who destabilize the entire region.
If you're not just "lol ancaps r dum" and are actually feeling disheartened that the message isn't getting through, consider the global perspective. There is no one governing body that controls the entire world. It is a collection of over 200 local, individual states that claims virtually all the territory on Earth. Even if you factor in superpowers controlling entire regions, there's still no one entity controlling the planet. There currently is no plausible plan for global domination by any group.
From there, our job is to work down. End hegemony of global and regional superpowers by supporting nationalism, break states into smaller states by supporting secession, and continue down the line by supporting localist movements until each property owner is his own ruler.
