A lot of accident analysis reads like this (air accident reports especially tend to read like they've come from a writer who's just discovered foreshadowing). And often there's a few points where it could have been worse. There's a reason for the "Swiss cheese" model of safety. The main thing to remember is there's not just one needle: it's somewhere between a bundle of spaghetti and water being pushed up against the barriers, and that's before you assume malicious actors.
Yeah I get that, it’s not a single Voyager, it’s millions of them sent out radially in random directions and random speeds and one or two of them just happen to thread the needle and go on the Grand Tour. It’s just an impression. Plus as you say there’s the selective element of an intelligence deliberately selecting for an outcome at the end (which confusingly is also a beginning).
