It's also terrible for failure modes. Planets are independent of one another, this ring is one fragile entity. The largest destruction of life by a single unfortunate event in the entire universe made possible by one design decision. We know it's not indestructible (and can't be unless it's a fantasy novel with "magic"), I only read the first book and there were two large holes even in the tiny section they explored. Whatever happens to that hole in the ring that they find when they first encounter and land - crash - on the ring? Air is constantly lost through it. Not the one with the ultra-high "mountain" near where they crashed, the other one further along their route with the weather pattern caused by this air-loss storm. How is that sustainable - given the ultra-long time horizon, surely billions of years, that such a structure should be able to support life for (if a planet can do that much)?
