I love this analogy, and it's definitely a perspective to take seriously. "It's always okay, until it isn't" is something to consider, as is the idea that civilization is living on borrowed time, or borrowing from the future to pay the present.

I don't know if it's true, or if it's even something we can falsify at any moment in history, but stable civilizations have collapsed, and it's worth understanding that it could happen to ours too.
