I don't like being the "to be fair ..." guy, but if your argument is that sometimes, when perturbing a system, it may come back to rest at a different equilibrium that is much less desirable, it suggests that sometimes it may come back to rest at a different equilibrium that is much more desirable.

In fact, such a distinction might characterize the difference between pessimism and optimism.

That's exactly how we got humans rather than the objectively better rulers of the planet, the dinosaurs.
