Individual secession is THE most critical secession. Fracturing of nation states along ethnic lines will bring us closeR to this, but it is not a truely desirable end. Collectivism on any level will (as you stated) suppress individual rights. Look at american indian reservations and how they operate as a "tribe" - they are "sovereign nations". They have an ethnic or tribal identity, but how does that really help them, except to form a victimhood identity and seek aid from the US as a nation, and remind others of past wrongs generations ago? The only meaningful point I see is to preserve social norms, to encourage family and community cohesion through tradition. But they are a formality in the lives of most at this point, not really a useful binding mechanism. The victimhood identity is much more powerful and alive today - from my point of view as a non-american-indian. Granted, the ancestors of them were mostly, exceedingly victimized.. certainly not more so for them than anyone else today. Like black Americans.
