We defeated the British without consolidated government.
No, we had a confederated government, although not a very well organized one. Hey, there was a war on. It's hard to organize a new government while you're fighting a war, worse yet fighting a war on your home terrain. (Rule number one: when fighting a war, try to do it on the other guy's territory.) And we had French and Spanish help. So we won. Barely. If there had been thirteen separate governments each fighting the British separately, well, you could expect to know what spotted dick tastes like, as well as kidney pie.
But you seem to want disunion, to think it's a good thing.
