Perhaps a bit of the difference between us might be resolved, as I note what seems to be a misunderstanding of my conception of the technological development and concomitant increase of personal agency ongoing.

"You envision a future, derived from this pernicious system..."

No. Prior to the advent of states, centralization of wealth and power was far less potential, as parasitization was also, and folks retained their own to far greater degree. History has been both deliberately obfuscated regarding such societies, and otherwise largely lost from our purview, so we can know little of societies largely free from parasitization that have previously existed. We can be certain they did, because parasitism depends on numbers, and many societies existed which did not concentrate nominal numbers to support parasites, if for no other reason (and I can think of many, besides).

After the industrial revolution, centralization of wealth greatly increased, facilitated by greater wealth withal, as the increase in technology delivered to ordinary and overlord alike more and better goods and services, except as inequity and corruption continued to debase the ordinary to favor overlords.

While continued advance and development of technology is the basis for my predictions, it is not based upon mercantilism, but rather upon the crafting society that pre-existed the industrial revolution, because that is the production, distribution, and wealth creation mechanism it most resembles. It's just a vastly improved wealth of goods and services than handwork makes possible. Security technology prevents the parasitism that centralized states have heretofore committed, because WMDs aren't suitable to making slaves obey. They can only eliminate them, and with them the potential profitable parasitization. Weapons wielded by individuals are necessary to subdue and force their victims to obey, and as security technology has evolved it has become impossible to such a gang of thugs to survive nominal defenses and even get within range to deploy their weaponry. Firearms are 1000 year old technology, and there is a reason that they are how wars are fought, and how police gangs are armed. It's the peak enslaving tech that is possible.

More advanced personal arms utterly preclude gangs of thugs, and through various institutional mechanisms, such as censorship, understanding of such tech has been concealed. The advent of personal means of production enables folks to not only make them themselves, but to invent them. Clearly overlords had no interest in even allowing such tech to eventuate, as it destroys their ability to parasitize their victims, much less mass produce it.

I won't go into much detail here, but with a moat of microwave ovens around my home, no unwelcome persons would overstay their welcome, nor ever approach without my assent. Firearms have been obsolete for a long time, and I cannot count other security mechanisms that preclude their utility by thugs. Today we buy all our microwaves from merchants, and they don't sell moats of them.

Free men will make moats of them, and far better mechanisms to ensure their security, and it will be impossible to project force as a result.

It is not ordinary folks that have effected such antisocial measures as Enclosure, or The Clearances of medieval Scotland, or war. It is overlords empowered by those merchant scum we both revile. Ordinary folk in communities I have been part of tend to be pretty good neighbors to each other - where none employ nepotic connections to overlords.

It is overlords and merchant scum that rape this planet, society itself, and who will never debase the breadth of the universe similarly, because they will not command hordes of hapless slaves to do it. Free men working together have no interest in such rapine, except when availed of the ability to parasitize their peers and thereby become their overlords.

Decentralization is the end of such parasitization, and of the very way of life vampires undertake. I don't see decentralization as derived from centralization, but the end of it, and a restoration of the natural relationships between individuals in society, nature, and whatever gods may be.

Freedom is our natural state. Slavery is the hell that destroys the soul.
