The page says the bundle could not degrade gracefully. Then the Enlightenment keeps equality, dignity, and rights after dropping the metaphysics: "all souls equal before God" became "all citizens equal before law."
That is a degradation path. The moral piece survived the physics piece. If those intuitions are still what liberal institutions claim to be for, purpose did not go vacant when the cosmology broke. What broke is the advertised derivation.
A state that cannot justify its premises, and a state whose budgets are run by counts, are different leftovers. The Enlightenment sentence is evidence for the first. It is not, by itself, evidence that GDP inherited the purpose.
If dignity-and-rights is still the claimed purpose, the vacancy the proxies inherited has to be shown as a later event, not as the shatter.
