I think day hikers who think they have everything figured out for a long term survival situation are the most retarded ones. People who go hiking for fun and camping a few days think that their short term, more short term survival experience, under modern controlled short term conditions, is the best way for every scenario.
In a long term disaster, the smarmy ass day hikers and the kids running around with their light weight survival gear will be in a terrible spot. They are only prepared to survive for a short time WITH THE ENTIRE PURPOSE OF REACHING STEADY AND STABLE CIVILIZATION ONCE AGAIN and not survive in a long term temporary camp style situation they might end up in during a long term major crisis.
During the so called "SHTF" ( I hate that term) its more likely you will see people being displaced and many large areas in turmoil, which means you aren't just going to be hiking through the tame wilderness for a week back to stable safety, your concern ins't having a light backpack for your fun ol journey, you might end up in a camp for displaced people for a long time, meaning your heavy weight, and heavy duty, gear is far more important than keeping a few nice little convenient light weight, and light duty items.
The man who takes a full size wood splitter, full size cast iron dutch oven, full size tent, heavy duty cot, heavy wool blankets, big boi sleeping bag, full size EVERYTHING will be in a great situation to survive and thrive in a long term temporary camp or settlement than Johnny "Fancypants" Backpacker with his light duty garbage that's only meant for his fun excursions. His light duty aluminum cookwear, his light tools, his LACK of tools, all to save weight while he's jerking off in the bush on his weekends, aren't the best, and often times won't hold up, against long term survival use if the situation means others can't help him survive once he finds a place to settle/camp/stay.
The backpacker will mock the cheap Lodge cast iron pan for being "outdated" and "heavy' and stupid, till the backpacker's expensive lightweight spaceage shit isn't the best to live off of in a refugee settlement. Next thing you know authorities and others can't equip you with better more permanent survival equipment.
The minimal backpacker might die, or at best suffer in displacement that lasts more than a week, or may last months or a year. Once he realizes this isn't his usual fit backpacking trip, it may dawn on him the shortages, the weaknesses of his planning and strategy. He prepared for an easy week of hiking, and soon he finds himself for want in a month long, year long camp.
Think long term refugee if you have to move, not your escape from the city week long hike. Think bush craft, think pioneer survival and thriving and not just tide you over for a few days survivalism. Think about not having access to more permanent equipment when you start thinking about a pack or what you will take with you. That thing you left behind for your lightweight setup might be the thing you wished you took with you, you wished you trekked and trudged with that extra X amount of pounds once you got somewhere for a while.
Backpackers think their kool kids hobby is the ONLY and PERFECT method for what might one day be the real thing. Ill prepared nonsense.
