I like your train of thought here, it's a good "noodle". If I might add some more to the noodling... :)
I see an interesting alignment between the trends we are seeing in technology and politics. Actually, my senior thesis back in college (2003) was that the politics of information technology are disruptive to organizations. Not necessarily disruptive in a "sided" sense, in that "disruption" can be considered good, or bad, healthy or damaging, or both.
There is a trend we see in information system/technology architectures towards "decentralized" and/or "federated" solutions. For example - "service mesh" [1] or "data mesh" [2], both higher level stack abstractions that came from lower level mesh networking concepts. And we even see "mesh" concepts in the form of knowledge graphs, social networks, peer-to-peer, etc.
If you read up on this you will often see the word "federated" and it is so interesting that federation is both something we apply to technology/systems as well as political. I am quite sure that it is part of the key to what you are thinking about. There's a reason that countries have been referred to as "federations", why we call it the U.S. "federal" government, etc. I believe, among other things, it largely revolves around how one implements governance and ensures a working "system" in terms of standardization/policy.
There is a desire to be autonomous yet interoperable, and this applies as much to "human" systems as well as purely technological systems. There is a link, after all, between how humans implement systems per Conway's Law [3] - organization's systems often are designed to mirror their communication structure.
Institutions are just one kind of organizational unit, and there too you come across all kinds of interesting issues that have perhaps, barely been explored - one such example is "institutional trust" [4].
In summary, my own latest "noodling" on this area is that actually, our technological and political systems are still very much evolving. When you take into context the possibility that it is truly becoming possible within, how about we say, the next 100 years - that humanity my be able to truly exist off the Earth, in space, for longer periods of time - then that is going to open up a whole world of questions about these very systems which we think we have completely figured out.
If there is one constant I think we can count on, it is probably change - but, ultimately survival (a key element of which is adaptability) will probably be the force that drives whatever the next 100 years look like - and that could be both good or bad overall for the development of new organizational structures.
Personally, I feel that all of this is interwoven together in quite an interesting way and all related, as information systems are the backbones of organizations.
