Structures are political, politics rise naturally where human interactions (especially indirect interactions) exist. The question is how to make sure that politics are based upon and executed according to facts and principals like plurality, equal rights to human dignity and mutual respect. It's sort of obvious today that democracy as we have it is not workin like that, and that big structures like countries are hard to keep clean.

Exactly. On HN I expect people to guess that the current structures aren't "scalable" (sorry). So maybe a nice deep tweak to trim the fat, reduce height, simplify energy currents to avoid corruption, bureaucracy, endless bipolar swings ..

We have the technology we can rebuild it. (actually I think the solution is lo-tech.. basically prolonged discussions, hard, but not impossible)

In such discussions, its usually forgotten that how smooth modern travel and migration is. Just make it more smooth/quick then concept of libertarianism/socialism/etc becomes increasengly moot.
