I keep most of this in a cooler or in the trunk of my car and then I have different bags/totes/rucksacks ready for whatever situations. I try to keep things as versatile as possible and interchangeable, so that if I lose one thing I have a different tool to fall back on. Some of this is my EDC which is a small shoulder sling. Almost every bag I own except the shoulder sling has a pair of clothes hidden in a pocket somewhere.
Quinoa - 3lbs
Beans - 13 bean mix
Tuna
Water - 1.5L bottle
Coffee & Teas - Green tea, Cinnamon Ginger, Detox Cleanse tea
Knives/blades
Rope - hempwick
Batteries - some of them solar powered and have flashlights
Steel wool - can start a fire when short-circuited with a battery
Flashlights - a lot of my batteries have flashlight accessories or features built-in
Lighter, matches - preserve these with the hempwick
Vodka - for cleaning, sanitizing, and intoxication, or some other ****
Coconut Oil - same as the vodka without intoxication and is good with the food
Smoking materials - papers, loose leaf, filters
Hat - 2 different hats, one for cold one for sun
Gloves
Clothes - think 2 outfits per pack
Boots or sneakers - basically keep the alternate one nearby
Can opener/bottle opener/hand grinder
Multicook utensil - or multiple eating utensil
jetpack stove
2 contigo mugs- doubles as a pot, thermos, mason jar (actually I lost one this weekend RIP |I )
French Press - doubles as a pot or cup, it's coffee mug sized
3 different cell phones
cheap laptop
A bunch of blankets - moving quilts and sleeping bags
towel - doubles as a pillow
Walking sticks that I've collected from various places
Most of this is all camping gear or camping designed so it will all fit in roughly 3 different sacks (minus the blankets and walking sticks). I also have a harness with memory foam to hang stuff off of me with carabiners if i know it will come down to that. Definitely will hold you over for awhile.
Edit:
I had to go look at some of this stuff. This is real life.
Coffee grinder - handcranked
Tea Infuser
herbal kit - garlic, tumeric, cinnamon spice
powdered peanut butter
honey
hand shovel
fishing string
wire saw

The ironic thing about all of this is that my car isn't running.
