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.
Because we don't know what number less than 2.1 million population constitutes a sufficient number to declare independence, a proposed recognition of the right of 9 million people to declare independence won't work?
Are you insane?
