Great conversation!
I guess it would be boring without any opposition. Its like saying, "No war, no peace!"
Our lives won't be strong if no obstacles are coming on our lives. Battery for instance has a positive and negative terminals that makes up a voltage. Contradictions, debates, lefts and rights, good or bad. All of these stuffs makes our world perfect. For God believers, why satan existed in the first place? Why God just created all good. At this very moment, God can change the world right away, in an instant right now, because He's God. But HE doesn't do that? Why? Our being human could not comprehend everything, our will is not His will.
About centralize and decentralize, the word itself decentralize came from the the root word centralize, which means no decentralize without centralize. It would be a chaos in real life distributing all the money/resources equally to each and every individual and it would be impossible to happen in my opinion.
About enforcing laws and discipline, its necessary especially for those who use freedom abusively. Too much is too much. Even too good is not good.
. With freedom comes responsibility. I would suggest that a free people would behave a lot better than you give therm credit. Government may or may not be needed. However we should all be free to decide if we need it or not. But what we could all agree on, is that we do not need a one big central gov't. That is our biggest enemy at this point. We already have 50 states that are aready organized and no one would have to do anything new but just enjoy our new freedoms. Now if you want to expand on that freedom, guess what? You would be free to do so, or not.
