That's good too, but you have to have some way to tame big entities, like mega-corps, that have much more power than any independent government.

For example, mega-corp says to the citizens of indi-govr1: "hey, guys, you give me 100% tax break, and the ability to use materials bad for the environment in my factory, or I take my business in another indi-govr".

Without some framework so that such things cannot happen in ANY indi-govr, you are at the mercy of mega-corps...
