Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
Hate to break it to you, but your dog probably has a better chance of making it through a total societal collapse than you do. A quick Internet search of "dog survives" lists everything from drowning to being shot, from bear attacks to war -- whereas the closest you've ever come to "surviving disaster" is getting your wisdom teeth pulled, and even then it was only with the help of a cadre of trained medical professionals and a carton of the strongest painkillers on Earth.
Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper. Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses, have been suggested for survival retreats.
Having the right companions can mean the difference between survival and death when disaster strikes. While it can be an “every man for himself” scenario during this time, it’s still safer to be with people you trust literally with your life. We hope this post will help you identify the warning signs for the types of preppers you should avoid when SHTF.
Tenacious Tape is not the kind of survival gear you won’t use every time out but when that rogue branch falls on your camping tent and rips your fly you’ll be thanking your lucky stars you have it in your bag. It can prevent a difficult situation from turning into a life threatening one. Tenacious Tape is completely weatherproof and won’t ever wash out. It doesn’t leave any tacky residue and is also machine washable. It’s the kind of quiet innovation that elevates the outdoor experience for everyone without making a lot of noise and is essential survival gear for any outdoor aficionado. Available in 3” or 20” rolls and a variety of colors.
Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).
This tactical flashlight fits neatly into the palm of your hand so there’s no excuse for not making it part of your survival gear. It produces 300 lumens of intense, focused light, has 3 operational modes – high, low and strobe (particularly handy in emergencies) – and is tough as nails so you don’t have to worry about damaging it. It’s the kind of rugged, dependable companion you want with you if you’re lost or injured and it will greatly increase your chances of enjoying a successful resolution to your situation.
Modern-day survivalists aren't generally regarded as the most sane people on the planet. A quick look at any one of the disturbingly common and frighteningly thorough shopping lists they post online drives home the fact that anyone who self-identifies as a "prepper" most likely went off the deep end a long time ago. Sure, it's fine to keep a few extra cans of food and cases of water around for an emergency, but if you start adding body armor and butt paste to your stash, you might want to tell George Miller that it's time to see other people.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
With the world seeming to become a more volatile and dangerous place with every encroaching year, it can be hard to know exactly where you can feel safe. The modern media is overloaded with stories about violence, crime, and sensational pieces on the worst people in our society. But there have to be some places within the United States where the chances of anything like that happening to you is next to impossible, right?
