There will never be a world in which there are no rulers. Human beings, indeed the entire cosmos, is hierarchical. The issue isn't rulers, the issue is unrighteous rulers.

Put another way, if the State doesn't see itself as being under the lordship of the God of heaven, it will elevate itself to be in the place of God. The issue is not fundamentaly that there are governing bodies and authorities, it is that, in our age, those authorities are godless (and therefore tyrannical).
