That does not change the fact that the math is pretty solid and it would work.

You haven't done the math or cited any.

There is a big efficiency problem in space-based solar with the double conversion from DC to RF/laser and back to DC. Total efficiency neglecting transmission loss is about 64% (80% twice). Then you have to invert it back to AC usually, but that is also needed for terrestrial solar.

So 35% power is thrown away, but since the sun is stronger in space without atmospheric attenuation, and there are no clouds, some of that will be made up.

So to a first approximation the power per unit of panel area is the same from space as it is on earth.

Now factor in launch costs which are tremendous (even if SpaceX succeeds in yet another 10x reduction in launch costs as claimed) and the difficulty performing maintenance in space versus on land, and I don't see a strong case. Installation costs on land are around $1/watt, I'd like to see you come within a factor of 10 of that in space.
