I agree. Anarchy might work in a little cult community, or to replace an HOA in a gated community ... but even then you're talking about a lot of people with resources and vested interest.

The computers (or phones) we're typing on right now, and the networking infrastructure that makes global community possible, does requite a State (multiple states). You cannot have technology at the scale we have without institution some type of governance. You can't have interoperability without standards. Something as simple as the postal system, or as complex as Interstates/Autobahns, still requires a functioning State to work.

Anarchy doesn't scale.
