You are speaking an Alien tongue right here. I cannot even make a stab at your meaning. It is literally off the map of my comprehension. It is a concept so foreign to my understanding that I must conclude you have suggested it in error.
That is why you get flustered if anybody asks you any practical questions like how should the existing government should determine which declarations of independence that it must honor and which declarations of independence it may properly ignore.
No, If I get flustered at all, it is because such a question is beyond asinine, it is a deliberate attempt to ignore the larger point, and that larger point is that the Southern States more than met the threshold set by the founders in both Population and Geographical area.
What is the point of speculating as to what number consists of Sufficient, when we must take it for granted that the Population at founding must have been so regarded? Why spend an instant on the question?
Because without answers to those questions, your proposal won't work. The government will get 50 declarations a day, many by people or groups who are crazy enough to believe that they are serious. Your proposal is unworkable in the real world. If they put you in charge, you wouldn't have the slightest idea as to which declarations should be granted and which should be ignored.
And, because it is so obviously unworkable, I know that not one of the serious people who signed the Declaration of Independence would have supported it.
If you and your allies want independence, you either have to gain independence by agreement (negotiation) or by force. There never has been any other way and there never will be any other way. And, really, grownups have to wonder why you would try to imagine that there is some other way.
