Not all the utilities Paul, just the most vital to survival, the rest will come as they do.
If an event was so big as to wipe out the kind of numbers that would be needed to destroy all knowledge in every field of modern day comforts then new-old ways of thinking as you've suggested closer to the earth will be more effective until lost skills are rediscovered or the once modern world is reduced to ruin.
I'm also not suggesting that I will take up a personal crusade to be a new world saviour. But to pose the question on how people see this being accomplished and in what priority?
Ahaha I thought you might like that
It is my belief that to be prepared information must be deseminated and distributed as quickly as possible to those that have the ability to teach and deliver those lessons they learn
Those that can not teach must be taught to act that can not act must be protected that would mock ignore and harm be addressed.
