That's not really an accurate description of why the states were established. The initial states were the consequence of different centers of colonization and the limits of transportation and communication speeds. Their borders were mostly arbitrary geographical boundaries (hey, there's a river!). They developed unique economic and cultural traditions based on what could be grown, produced, or not, in their borders. That people didn't want to join them up into one stronger federal government has stronger ties to the general tribal nature of people and the significantly different economic and cultural needs. Movement between them was hardly the motivation.

To be fair, one of the reasons was to limit the power of the federal government. But that power was limited partly in order to prevent one state from having power over another; that's why the Senate is so laid out (http://en.wikipedia.org/wiki/Connecticut_Compromise), and one of the reasons the federal government is seated in neutral territory (Federalist #43).
