It's a perfectly reasonable example. Most complex systems share those properties. It makes glaringly obvious that isolating blame/personal responsibility has limited effectiveness in preventing accidents. While we need a blame assignment system that's clear to reason about for financial reasons, for other systems where that need isn't so great, more effort ends up getting spent on figuring out how to prevent outages than assigning blame for them.
