I can agree that this is interesting as a thought experiment, and indeed could form an amazing foundation for an ambitious work of fiction. But the only way to bring about such a world IRL would be by force, meaning that many people in such a society would perceive it as a highly oppressive state.

To get the paradigm shift you're after, and a collective consciousness, you'd have to have buy-in from every member of such a society, and to raise children in the same principles. Perhaps it could be a civilization on an island, or the founding principle of a generational starship or something.

The Borg were supposed to be a cautionary tale, not something to aspire to.
