That's still a smaller ratio than the ~4X gain in irradiance over LEO. But if you're doing it at scale you could use orbital tugs with ion drives or something, and use much less fuel per transfer.

It's probably not competitive at all without having fully reusable launch rockets, so the cost to LEO is a lot lower.

8 tons over 22 is a little over 1/3rd the original payload to LEO. If 4x the solar generation potential (not irradiance - the sun is not 4x brighter in space at Earth's orbital radius) is the reward, that's putting an incredible premium on a 3x multiplier on launch costs per kg (at minimum - likely higher, you're also inheriting a worse radiation environment).

But those two parameters are not equals: 3x the cost per kg is a much higher number then 4x the solar power.

My response is already contained in my comment above, in the sentences after the first.
