The kind of gear you need – It’s easy to get obsessed with survival gear and start accumulating every new product that comes on the market. If you have money to burn and engage in a variety of backcountry activities this might be a sound strategy. Most people however decide pretty early on what type of outdoor activity floats their particular boat and as such any survival gear should have some sort of relationship to that activity. Everyone, for instance, should have an emergency whistle with them but not everyone will need an extreme sleeping bag. Everyone will need first aid items but not everyone will need to carry croval shovel or a tactical watch or field watch. If you’re a mountaineer you’ll probably want that shovel, especially if you’re climbing in the winter. If you’re going on a day hike and aren’t bringing food that requires preparation there’s no need for a mess kit and so on.
In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sun glasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.
Sometimes there just isn’t the material available to create an emergency shelter. In that case if you have the Survival Shack Emergency Survival Tent in your survival pack you’re ready. With all the heat retention ability of the Mylar emergency blanket and the ability to provide real shelter in just minutes the Survival Shack Emergency Tent is genuine survival gear.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
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?
Lifeboat survival kits are stowed in inflatable or rigid lifeboats or life rafts; the contents of these kits are mandated by coast guard or maritime regulations. These kits provide basic survival tools and supplies to enable passengers to survive until they are rescued. In addition to relying on lifeboat survival kits, many mariners will assemble a "ditch bag" or "abandon ship bag" containing additional survival supplies. Lifeboat survival kit items typically include:
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
For personnel who are flying over large bodies of water, in additional to wearing a survival suit over cold water, a survival kit may have additional items such as a small self inflating raft to get the aircrewman out of cold or predator infested waters, flotation vests, sea anchor, fishing nets, fishing equipment, fluorescent sea marking dye, pyrotechnical signals, a survival radio and/or radio-beacon, formerly a distress marker light replaced by a flashing strobe, formerly a seawater still or chemical desalinator kit now replaced by a hand pumped reverse osmosis desalinator (MROD) for desalinating seawater, a raft repair kit, a paddle, a bailer and sponge, sunscreen, medical equipment, a whistle, a compass, and a sun shade hat.
I’ll take a person with common sense over one who has a lot of survival knowledge and skills. There is too much emphasis out there on wilderness survival. That will be a rarely needed skill set. More common will be urban survival, and suburban survival. Age and physical condition will have more to do with being able to survive a long-term disaster. As a senior I have difficulty convincing myself and my peers that hard core survival skills will be possible or necessary. We can only prepare for those things we feel we have any chance to survive anyway.
The U.S. Department of Homeland Security (DHS) in their "If You See Something, Say Something" campaign says that "the public should report only suspicious behavior and situations...rather than beliefs, thoughts, ideas, expressions, associations, or speech...". However, it is alleged that a DHS list of the characteristics of potential domestic terrorists used in law enforcement training includes "Survivalist literature (fictional books such as Patriots and One Second After are mentioned by name)", "Self-sufficiency (stockpiling food, ammo, hand tools, medical supplies)", and "Fear of economic collapse (buying gold and barter items)".
Lightweight survival kits are generally seen as a backup means of survival; however, these can kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.
The most dangerous people in a survival situation is the gang of outlaws who only want to take what they need and don’t care about what happens to the owner(s). The hardest to know what to do with, and for, is the individual (person or family) who has done nothing to prepare for emergencies or disaster. It’s hard to want to help someone who does not, and will not, help themselves. But it’s endemic to our society – it’s all about big brother taking care of you, or “the government” being your friend. It’s about entitlement. It’s about not caring about other people, only yourself/family. They are the 2 true dangers to preppers.
And, of course, people aren't going to stop wanting to get drunk just because they can't pop over to the corner bodega for a six pack whenever the urge strikes. Portability and long shelf-life make liquor of all types a valuable trade good -- people will kill to get a taste of the delicious bottom-shelf leftovers from your local dive bar when their only other option is the equivalent of prison wine.
