It took 16 years to build the network to where it was, it’ll take a long time for it to fall apart. Think of it like a train network. Imagine if the NY subway lost 3% of its stations, and some riders who either went from or to that station stopped using the subway. People might say “oh, it’s no big deal, just 3%, it’s still super useful to have a subway.” But then those riders that stopped using it are no longer using the other stations on their trips, and it’s then 3% harder to justify every station on the network. So any station that was borderline not worth it before now becomes definitely not worth it, and those drop. So now it’s 6% lower, and so on until there’s no stations left.
