I would also agree that one cannot feasibly carry all those things that would be needed in escaping from a high density area to a rural/country area, but that's where the prepping thought process begins.
Some citybound folks have gone so far as to buy a separate bugout piece of property in the country and have living facilities (camper, trailer, vacation cabin) there already stocked with the essentials. But like you said, most folks may not can afford that option. Hopefully, in the alternative they have family or friends that live in a rural area that have all the essentials at their household so that whatever you can bring, whether it's additional food, medicines, silver, ammo, etc. will at least help add to the stockpile of goods. Again, that's why it's so important to have that group that can rely on each other, to lessen the burden of each individual from having to provide everything one needs.
Sorry to get so verbose. It's an important issue with me.
I don’t believe it’s the peole, I think it’s the fact that this is the 21st century and what makes that way of life viable, just is not possible for the number and location of people we have today.
I doubt that many people that are 3rd or 4th generation, living in the big cities, still have family or friends living in the country that can be relied on to provide a new way of life that may be necessary.
I understand your fervor, but unfortunately, I think you are preaching to a very small choir.
