If we are talking long-term survival, then the list changes considerably. Add in firearms (an air rifle with about 10,000 pellets and some proper oil and a cleaning rod are invaluable), seeds for common (heritage, which propogate from seeds next year) vegatables, dry stock as listed above, and water filters, plus some hand tools for working with wood, dealing with butchering, etc.
We wouldn't have to reinvent the wheel if the lights went out for a long term -- houses, rv,s etc., are still there -- so all the woods lore about building your own home from trees and such is probably not well thought out -- but a lot of what we currently use would need to be radically re-purposed. Our gutters, instead of dumping rain water to storm drains, would need to be diverted to water storage. Furnaces that run on LP or oil would need to be converted to wood, plus tools are needed to process that wood. Even our RVs would be of limited use if the power went out long term, as they presuppose an ability to move, and that would no longer be the case.
With a decent air rifle, a grill, and a couple of hand tools, a person can live, even in the city, for a long time without the grid. All sorts of good-to-eat stuff flying and running around.
