I mean yeah if you consider the "scale" to not be a problem there are no problems indeed. I argue that the scale actually is the biggest problem here... which is the case with most of our issues (energy, pollution, cooling, heating, &c.)
The real question is not scale, but if it makes financial sense, I don't have sufficient insight into the answer to that question.
Either it does or it doesn't make financial sense, and if it does the scale isn't the issue (well until we run into material shortages building Elon's Dyson sphere, hah).
