In essence, the idea is to institutionalize “voting with your feet” by ensuring that when some snarky devil, says “OK, don’t let the doorknob hit your butt on the way out. Good luck finding a place to go since you can’t have any territory!”, you can say, “You’re talking exile and what has been institutionalized is secession. Webster’s has something to say about the relationship between ‘secession’ and ‘territory’. Look it up, you snarky devil you!”

From the intro to that essay:

Secession is necessary to free society. Free society starts with mutual consent. Mutual consent implies the option not to consent. “Freedom From” compliments “Freedom To”.

Secession is necessary to true social science: We can best discover causal laws by testing theories with controlled experiments. This is true of all science. Controlled experiments require separate experimental groups, treated according to different theories and comparing the measured results with predictions. In practice, human ecologies can form separate experimental groups only by upholding geographic boundaries that prevent cross-contamination between treatments – cross-contamination with its resulting confusion and confounding of results. We can argue how best to achieve this in practice, but the principle of giving experimental evidence priority over any amount of argument, debate, deliberation, peer review or judicial proceeding stands as more self-evident than anything in the Declaration of Independence.

In a free scientific society, an individual is subject to treatment only after giving informed consent.

These two pillars of social good — truth and freedom — stand upon the foundation of secession.

Tyranny of the majority, limited only by a vague laundry list of selectively enforced human rights — the sine qua non of “liberal democracy” — must submit to the right to secede or it violates truth and freedom, hence all social good.
