Still I do remember a slower time when 7-11 was the only thing open on Sunday or outside of 9-5 otherwise, naturally it was open from 7am to 11pm.

What I mean is when you see the way that thousands of people across multiple disasters react to complete loss of power for an uncertain period, it depends strongly on the confidence in abilities to survive without very much beyond the bare necessities. Probably just as much as the actual abilities.

To me this makes post-industrial survival exercises as worthwhile as some of the paleo enthusiasts have reported here about their experiences already.
