There's a paradox here, the problem and the solution, is literally wholesale asset destruction. We'd have to abandon a lot of infrastructure. A good portion would even need to be recycled, not for reclamation, but to prevent ecological disaster ensuing from its just rotting in place. And that's sorta why we get entertained with cataclysmic scifi themes, because it gives a "no choice" instigator for that asset destruction. But doing this by choice and quickly? Difficult.
