I would never want to live in such society
It doesn't work just like that.
Currency: you need it as the blood of the economy.
Government: you need laws, because some people are always assholes. And you need an authority to enforce those laws to avoid a state of anarchy. (The political system itself could use tweaking, of course.)
Culture and religion tend to go hand in hand, although they don't necessarily have to. But people do need something common to believe in; if it's not a deity, they still need a common history, a common purpose. With no great beliefs to unify the people, the society falls apart.
Problem with the last bit is that all cultures, religions, and beliefs are not equally good; some are utterly shit and worse than all others. And we need to be able to say that aloud to keep the shit out of the society.
I think you're hitting some of the points in the problem...As a WoW player, I've looked at how some of the cultures we knew were worked into the game, giving some things a theme/flavor, such as Norse, and Egyptian beliefs, merging into the titan technology. I just would think if cultural relevancy could influence how technology is viewed...we might find a progressive point.
Impossible to make the world better as it is, this society is doomed and lost. Nothing good will come from it, what we can do though is take all the technology and knowledge we've amassed and create a new society of humans with that technology and knowledge. A clean slate.
You might want to go to those scientists and tell them that everything they've been theorizing about is techno-magic, you sound like a person with reasonable knowledge and authority on the subject.

So, why don't we go ahead and find out? Jump-start it right now, throw away money and pool everything together to find out if we can pull it off.
Change naturally happens over time. It's rational to react negatively when someone says, "Okay, starting from tomorrow, a totally new society."
Any big advancements will come through hard work and building on whatever we have now, not science fiction fantasies of social maladapts.
Your fantasy will never happen. It's not realistic, it's not accurate, and it's not well-informed.
And I'm glad for that, because if someone ever did create a population of humans like that, I'd hope the rest of us, or some other species if they exist, would have the good sense to wipe them out and put them out of their misery.

A new society will be plagued with the same issues of the old.
As long as humans have other desires they need to fulfill, it'll be impossible to create this system where everyone works together to achieve something like this.
This is the same reason why communism will never work.
The kind of mega-engineering required to make even a Dyson-swarm is way beyond what we can manage, and hopping straight to it is unecessary for a long, long time yet. Humanity needs to concentrate on space-borne or exo-planetary habitats within the solar system first, and I get the feeling the first real attempts at these will be made by the private sector to gather resources for profit.

Still, if we're going to essentially burn out the current society, spend all our resources and sacrifice ourselves we'd better be damned sure that these new-society seeds will work and are worth the effort. Personally I don't think it will be.

Because the act of trying, if we could get together the collective will to do so, could very well be economically crippling to the planet and set us back centuries.
