There will always be someone like me, who doesn't recognize the legitimacy of the vote. The act of voting may be voluntary, but the consequences are never voluntary - if they were, there'd be no need to vote.
Discussion
if you voluntarily agree to submit to the results of an election that you eventually lose, and then you participate in the vote, I consider that voluntary.
If you _don't_ agree to be involved in the election at all, that's a different story. Involuntary.
The fact that unilateral Exit from a "democratic" governance system is not permitted is the lynchpin. (And this aspect relies on the "territory is synonymous with the State" aspect. If it weren't for this latter part, you'd be able to opt out and stay home on land you legitimately own)
I'd always take that option. My land, my rules ; other dude's land, other dude's rules.
The option to opt out would be nice, but it would result in no democracy at all. People would get sick of losing and stop doing it altogether.
I'm okay with participating in votes with no opt out option if its a vote for my own community, and people outside my community are explicitly excluded. Anything beyond that, I simply don't recognize as legitimate, so if they want me in it, they have persuade me to go along regardless of the vote.
