You have any specific ones you can list? I love these kinds of things. It sounds about right though, and much like a foundational component that lead to Classical Liberalism (aka: what liberalism was in the 1700's).
Some of the downsides of the historical experiments are going to be in a lack of common currency for trading with "outsiders."

Things like replacements to central record keeping (house deeds, car titles, all forms of contracts, etc). Those that currently hold the centralized power are not going to let it go easily...
