Based on this crude but honest assessment of the general public's affinity for the common bicarbonate, you'd be surprised by how much survivalists are into it (#2 on the list of "things for preppers to hoard"). They must expect some pretty serious hankerings for tasty leavened baked goods, or they have extensive phobias about the funkiness of their nuke survival backup plans.
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.
This type of prepper prides himself on how prepared he is for any apocalyptic event. He finds it hard to keep his mouth shut about his food preparation, water supply, and his self-sustaining environment that he built as a whole. The problem with this is if a disaster does happen, those ill-equipped groups will surely come for these religious preppers first.
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.
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?
Every year in the US about 150 people die while out and about in national parks, more than 1,000 die in hunting-related incidents and thousands of backcountry enthusiasts get in deep trouble and require a Search and Rescue team to save them; with dozens of those folks dying while awaiting rescue. Most fatalities are the result of poor preparation. Bad weather descends and people get lost. They wander without water or shelter, often injuring themselves in the process. If they survive they often suffer frostbite, hypothermia, dehydration, trench foot or some combination of them all.
