Maybe because so far it has a preponderance of big talkers. They'll need people who are willing to use the words “we mutually pledge to each other our Lives, our Fortunes and our sacred Honor” or people who have none of that to lose. They may get enough of those people with some sort of catalyst or incident. They'll also need people who know how to actually run things. They may have more trouble with that.
If there is such a catalyst, some sort of “secessionist movement” is possible. It is not beyond comprehension that such a catalyst occurs, I enumerate some in a previous post.
What would cause you to revolt?
