> How would you design a system that simultaneously achieved all these goals:

There is an obvious solution that achieves all of these, that, on 1000 year timescales, seems inevitable: deprecation of the nation-state.

The internet solves every problem the nation-state purports to. For example, the very real problem of coordination, eloquently and convincingly outlined in the federalist papers (tldr: we need a central republic structure because it's too difficult to coordinate disparate statehouses via horseback with every little intrastate decision) is solved by dint of instant communication and long-term data retention. So it is with every other claim in favor of these huge legacy state structures.

In this age, there is no longer any state needs to be larger than say, 1500 square km - about the size of a large county. This way, people can flee on foot to an adjacent state if needed, and no state can possibly control enough infrastructure to force Vodaphone to send such nauseating propaganda.

We need the elder statesmen in the room to read the writing on the wall and begin this process.

Assuming a rectangle of 30 by 50 kilometers, and no organized military for defense, it would take the Russians about 30-45 minutes to reintroduce the imperial subject experience on your proposed utopia.

The reason states are required are that other people are organized in states. Now I am guessing you are from the US, the standard of your living is only made possible, by millions of men and women working seriously to guarantee it, and thousands of nuclear weapons. Take either out of the equation, and your standard of living will very quickly become untenable.

Hell, the internet that you believe can solve all the problems, is only operational because hundreds of thousands of people are continuously working on it, many of them government employees.

We need large nation-states to make the modern world possible. The internet isn't just bits; everything depends on stuff that has to be shipped by sea. It takes a hegemon like the US and its allies to keep the sea lanes open. Navies are super expensive and a collection of small states wouldn't be able to build ships that could operate around the world.

If anything, technology is making possible for states like Yemen and Iran to shut off chokepoints. It might take multiple powers working together to keep things open.

What happens when China or Russia decides to stay a massive empire and starts conquering your microstates? What happens when state A allows the dumping of pollution that flows into state B?

So you propose to replace the nation states with corporate governments. Okay, two questions: who gets to make the laws, including the property laws? and who gets to enforce those laws?

Given the vacuum left by pinhole-sized states, Vodafone could become the issuer of propaganda itself as it would have the airwaves and the power of a large state.

Nations organize themselves into states to protect and promote their interests, including their existence as cultural and ethnic groups, from competing states (and other dangers, e.g. natural disasters). A.k.a. politics.

I was not aware politics has been solved by the internet.
