I agree--there's an element of sovereignty to choosing your form of government as well, not just to running it. I mean, what if England had said to the American colonies "okay, you can be your own separate country. You'll have your own king, your own parliament, your own military, and so forth. Here's your constitution, here are your laws, go follow this plan and you'll be good." I do not think that would have worked out quite the same. It has to be the people's decision, they can't just be told which form of government is best for them.
