I don't think decentralized systems are always better than the centralized ones, sometimes having a leader or a reference point is a good thing. Though I love how decentralizing systems are solving the big mess our current world has became.

And when/if those systems become out of control in the future... A great centralized system will come to save the day... hopefully.

EDIT: Whoops, my comment had nothing to do with Star Wars but that's what I've thought when I read (parts of) your post.
