re: Should we build a Dyson Sphere to harvest 100 percent of sunlight?

It’s a fun concept, but the reality is that even in theory, it generally makes more sense to capture a large portion of the energy from a star, with an emphasis on direction, than it does to capture all of the energy from a star.
As I understand it, the theory is generally that a Dyson sphere would start as exactly that but then grow exponentially as the civilization has access to more and more energy.
By the time you get to a full sphere, the civilization is harvesting so much energy from the star that direct “natural” light isn’t needed anymore.
At least that’s how I’ve interpreted it, anyhow.

I have a hard time believing in the long term stability of a system in which entities take all the light from a star, but pinky promise to give it back to those planet side.
Can you imagine the doomsaying and riots as soon as the plan was announced?
