It’s really hard to wrap your head around the scale of the Ringworld. It’s way beyond anything people have experience with. From the surface it looks like any other planet (unless you’re near the edge and can see the wall), just there is a thin bright line in the sky all of the time and the Sun is always directly overhead.
The surface area available is just crazy. The reason we will never build one isn’t because it’s impossible, but because it’s gross overkill. Every person alive today could claim a land area approximately 230,000km^2, or roughly 1.5x the surface area of Earth, not counting the parts covered by water.
It’s good if you want to get away from it all, you could literally have an entire planet to yourself.
