I live in Connecticut after living in Florida. I can tell you this whole concept of everyone doing what they want in their own little sandbox doesn't work. In fact, during a disaster it is probably going to get people killed.

Connecticut abolished county governments a long time ago. Now, you have 140+ cities all doing their own thing. Regional coordination is starting out of necessity, but some people's opinions are that they usually start too late anyway. This is probably unlike what "Jefferson State" is going to do, but if we start fractionalizing things, that might be bad. Then again, there are only about 20 major urban areas in the United States. If they're separate and control their destiny like Jacksonville, FL ( they are both a city and a county effectively ) or those weird Virginia concept of independent cities.
