It s a crypto company, this increases the scam factor a tad.
We are not a crypto company. Moreover, being as clean and open as possible is the only way to win the battle of the good guys vs. the bad guys in supply chain.

There will of course never be a Dyson Sphere, or anything even vaguely reminiscent of it. Instead, long before anything of such a scale would be conceivable, we will have hydrogen-boron fusion for unlimited energy, and moved industrial operations out to the Kuiper Belt, where the truly valuable commodity -- cold -- is abundant. Suns and planets are for extreme rock-banging primitives.
Alternatively we could merge with the machines and all go virtual. But I am to believe that part of the humanity will remain explorers and will want to go beyond our star. That's where the physics kicks in. There simply isn't enough energy that can be mined and extracted from minerals.
This is, presumably, after you have fused all of Neptune and Uranus. I guess you could start in on Saturn, or Planet X.
I want to send something to a carbonaceous chondrite asteroid that can extract the volatiles and turn the coal-like substances and stony substances into large plastic (Kapton!) and metal films. These could be used for solar collectors, solar sails, sunshades. It pays for itself by manufacturing space sunshades to the Earth-Sun L1 point that get their own their own power. The "something" is probably a factory that bui…
Kapton requires a great deal of hydrogen to make. L1 sunshades would cement global catastrophe, as unrestricted accumulation of CO2 would further acidify ocean shallows eliminate the base of the ocean food chain.
I think some asteroids might be rather gassy and might require devolatilization before doing anything else and that is awkward because you are going to be at your bottom in terms of equipment inventory, particularly storage tanks.
As for ocean acidification it is a real problem but the severity of what we’re up against means we shouldn’t leave solar geoengineering off the table. The fact that one party could do something very dangerous in fact might break the ‘collective action’ problem.
I presented on this idea at a seminar on geoengineering and I was accused of trying to build a Dyson sphere, I said "no, there is not enough mass in the asteroid belt to cover the Sun but you can build something pretty big, possibly a human habitat much "bigger" than the Earth in land area."

Can you say more / link to more info about these "bad guys in supply chains"?
If you want to be more specific, you can google for "carrier haulage tax evasion" - this will be just the tip of the iceberg.
Supply chain is mixed with shady practices for tax evasion, bribery, laundering and all sorts of shady things at all levels that "compete" with actual process optimization. Combined with overall opposition to automation this incapacitates any effort to make the process efficient cuz it's hard, it "steals jobs" and not easy money.

Where do you hope to get your energy, beyond our star? This is, presumably, after you have fused all of Neptune and Uranus. I guess you could start in on Saturn, or Planet X.
1. Just beam it with a huge laser to the spacecraft (google for several proposed projects already in development and plans for launch) 2. Store it onboard the spacecraft and then use, with multiple options and different levels of today's technology feasibility like creating a small spinning black hole or creation of exotic matter for warp drive

My guess is that some CC asteroids may have generous amounts of hydrogen. Any reasonable plastic has a lot of hydrogen in it, kapton is harder to make than PE and PET and requires nitrogen which is more of an unknown in terms of a availability.

Heat is easy to get, fundamentally hard to shed.

By then we will have pB fusion, and have no need of solar arrays. The Kuiper belt will then be more attractive than the asteroids. There is plenty of frozen nitrogen there, and abundant precious cold. Heat is easy to get, fundamentally hard to shed.
My guess is that anybody who gets out that far loses interest in dry inner solar system planets completely and isn't going to be interested in exporting products back.

D + D probably wins in conditions out there. The T and He3 that it breeds will be handy. My guess is that anybody who gets out that far loses interest in dry inner solar system planets completely and isn't going to be interested in exporting products back.
Although other people might be the most immediate threat right up until the moment a magnetar sterilizes the vicinity.
I don't know whether we are certain where the nearest one is.

That is not true about the soil. Areas in Europe have been farmed for hundreds or more years and still productive.
I believe OP is referring to the impacts of climate change rendering farming unsustainable.
