It's OK that they don't last forever; they're schools, not irreplaceable shrines.
And speaking of things that also don't last forever: Homeowners. Grandma Sally isn't going to live forever. The house winds up on the open market in order to seek satisfaction of Grandma's debts, and then some new family buys it at market price and is free to breed a whole new fleet of kids to raise there.
There's still eventually churn in the marketplace, and in the neighborhood. The churn didn't disappear just because Grandma Sally was able to choose to keep living in the same place until she died quietly of an agonizingly painful heart attack as she stood in the kitchen making tomato sauce after church on a Sunday morning before the family dinner that afternoon.
People die all the time. It's often tragic, but it's natural and ultimately unavoidable.
People also get forced out their forever-homes all the time, too. That's also often tragic, but it happens for artificial reasons that could be avoided if we bothered with trying to do so.
That seems a bit ironic?

Not always, grandma can pass the home down to whoever. IIRC there are ways to do it without triggering a reevaluation on the original purchase price.
Anyway, Grandma is as dead as that Sunday dinner. She won't care that the new occupants are being complete heathens about smoking dope and makin' babies on the sofa.
