You are talking about decentralization - during a time of increasing pressure to federalize everything. Decentralization would be great. But, too many are interested in holding outsized power and decentralization challenges this.

And on the issue of break it all down and rebuild it - you are in good company. George Carlin said toward the end of his career that the only way forward was to burn it all down and start over. My only problem with this idea is that I don't think we have the kind of people in the US at present who would be willing to pledge their lives, their fortunes, and their sacred honor to create a democratic republic crafted around the rights of the individual citizen. Everybody wants to rule the world.
