I'd say the power to leave is also a nice feature, it forces the larger government to provide some sort of value and not step on too many toes or risk being disbanded. Imagine if California was free to regulate all of healthcare for itself. They could write whatever socialized medicine program the voters desired all while not burdening the people of Texas with the cost who perhaps prefer a free market solution of some kind. As different states implement different programs people would be able to vote with their feet as to what was the better deal, causing states to compete with one another to offer the best deals to its population. States are too small to effectively implement what they want? That isn't a problem as they can contract with each other and if that goes south look to the federal government to resolve the dispute.
