Well, the thing about Rapture is that it shows the folly of the whole objectivist philosophy- indeed, of the idea that any philosophy will magically solve all of society's problems.
Just like how communism sounds like a good idea on paper but is incapable of working in practice, objectivisim cannot work because humans tend to group around authority figures, which then try to exercise their new-found power, which then brings the entire objectivist establishment crumbling in on itself. Combine this with the de-regulation of vital resources and institutions(which does lead to declining quality, despite what any politician will tell you), and you have a recipe for anarchy in and of itself.
