SW's screed is a mish-mash of all sorts of proposals from all sorts of sources - some semi-sensible, some goofy.  Save up for the inevitable big earthquake?  A great idea!  In practice, though, any $32 billion-dollar fund won't be allowed to just sit there - the bureaucrats will soon find a reason to move the funds sideways into public-employee pension plans and similar more pressing needs than earthquake insurance.

Return public lands to pristine, pre-Columbian wilderness?  Put public employees to work, *tearing out* roads and bridges and pipelines and dams and waterworks, instead of building them?  An idea straight out of the Wildlands Project handbook.  (P.S.  - they won't be public lands anymore - the public won't be allowed on them, for any reason.)  

Population control and whoever is left, practicing local subsistance farming?   Straight from the anti-human philosophy of Arne Naess, last put into practice by Pol Pot.

Not a "vision", but an hallucination.  :-/
