A space habitat the size of a city would only need to last as long as a city, say a few thousand years at the very most. Plenty of time to build several more space habitats, or to completely expand/rebuild the original several times.

ISS is falling apart after only 20 years. Those giant space cylinder things from the NASA artwork are likely to be a maintenance nightmare.

Isaac Arthur spoke recently about air leaks in O'Neil Cylinders. He said they're likely to leak constantly, which turns out to be absolutely fine, and even fairly large impact holes can be patched up with years/decades/centuries of air to spare (depending on scale, obviously). Hollywood gets this sort of thing very wrong.
