For kit placed in low earth orbit, where it tends to come back down again, fuel to payload is greater than 20:1, so to get 100 million tons of payload up, so the "plan" specs 2 billion tons of fuel-- per year!
If rockets were powered solely by kerosene (not) and observing that crude roughly converts to kerosene at 10:1, then the "plan" requires 2 billion tons of kerosene times 10 -> 20 billion tons of crude per year.
Note that the world uses 365 million barrels of crude per year. A barrel weighs 300 lbs -> 6 barrels per ton, so the world uses about 60 million tons of crude per year.
The "plan" wants 333x world crude output per year, or maybe the 2-3x per year the total crude ever consumed by humanity.
(Never mind for how long)
And for what purpose? To access solar energy ??? in space ??? to power chips ??? used by optimus robots ??? "among the stars"
Sounds like "galactic" jerking off. But it's what Musk knows best.
Didn't Musk have a toy digging project on earth that was going to revolutionize Vegas holidays? But he gave up because it was too hard or he got bored before the project did.
I never found terafab beyond a hiring page for Tesla, X and spaceX.

I was off by a lot:
World oil is 6 billion tons per year:
100 million barrels per day times 365 divided by 6 barrels per ton.
The plan wants 20 billion tons per year, so 3x world output.
Ok, I am so wrong! Sounds totally doable!
Maybe start with a lunar civilization, and let things move on from there.
