Great post goldendawne, it appears you have included nearly all of the important items required. Should the time come where people have to utilize all of these skills, I am afraid the ability to survive by the vast majority will be very sad. The skills of which you speak cannot be learned in a short period of time, at least not by one person. It will take many people, learning these skills, then working together to assist each other in a community.
We must acquire all the knowledge we can as individuals but we must be willing to share and pass that knowledge on just as it has been in the past.
There is not any nourishment in an iPhone, but if you use the iPhone to learn how to produce food etc, then it has been a useful asset.
Hopefully people will read and learn from your post, to assist I have resteemed it.......................billytwohearts
