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

A Dyson Sphere only makes sense in the context of using a solar system as a fueling station. If you also need direct raw light from the star to sustain life within the solar system, a Dyson Sphere is Armageddon.
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.
