On your 1st point, absolutely the gaps narrow and a more level playing field develops. Not before it widens first to awaken most of us.

On freedoms becoming smaller, I would disagree. 'Governments' (city states, mini-sovereignties, communities or whichever new name they may become) should be incentivised to act in the interests of their people - like businesses treat customers today. People will gather around shared interests, not an arbitrary psuedo-nationality like we do today.

Therefore the theory is that MUCH more freedom will result not less. Given more economic resources are put outside the clutches of those demanding it and more into those that are offering a good value proposition.

It is a possibility that you're right - big tech authoritarianism could expand reach in the coming years - particularly if corrupt individuals remain at the helm of these fringe countries. However I tend to believe (along with the author that) the track-record for such authoritarianism enduring isn't so good, particularly not on such a grand scale.
