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?
If you live in an area that experiences natural disasters that could result in an evacuation, it’s crucial to have a pre-packed bag with sufficient supplies for traveling. Convenient “grab ‘n’ go” survival kits have everything you need to stay safe, and well-fed while making your way to safety. Food, water purification tablets, personal blankets, and other necessities are provided in a duffle bag or backpack, so you don’t have to take the time to gather supplies before heading out. Typical kits contain enough food and water for 4 adults for 3 days.
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.
I am guessing, I am the homesteader. Or, I would call it “shelter in place prepper”. Since, I am in advanced age, I don’t have the mobility of a 20 year old, to bug out. The problem, I see with a homesteader, is if you don’t have the arms and man power to defend what you, then it will all be taken away. Reason, I am into hiding food in plain site. Pecan trees, oak trees, black berry patch, mushrooms, and such.
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".

DIY home surgeons will be excited to know epinephrine can actually be used with lidocaine (a numbing agent) to restrict blood vessels for faster wound repair. (Note: Cracked in no way condones performing self-surgery.) When sanitization resources become limited, the speed with which a wound can heal will have a drastic impact on survival rates. The longer a wound stays open and bloody, the more likely you are to get infections. Infections have historically been some of the most deadly and difficult-to-treat medical conditions, and even today they are not always easily survivable.
We get that creature comforts will be ever more important as the things that used to make us happy slowly break and crumble around us. But do you really want to put a ton of effort into opening a bakery when everything is going to shit? And we hate to be the bearers of bad news, but no amount of odor elimination is going to stop the uncivilized world from smelling really, really bad.
The communications equipment may include a multi-band receiver/scanner, a citizens band (CB) radio, portable "walkie-talkies" with rechargeable batteries, and a portable battery-powered television. The power supplies may include a diesel or gasoline generator with a one-month fuel supply, an auto battery and charger, extension cord, flashlights, rechargeable batteries (with recharger), an electric multi meter, and a test light. Defense items include a revolver, semi-automatic pistol, rifle, shotgun, ammunition, mace or pepper spray, and a large knife such as a KA-BAR or a bowie knife.
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.
Regardless of whether everything is going swimmingly or you’re lost in a whiteout above tree line your boots are one of the most important pieces of survival gear you have. You need them to stand up to the elements and keep your feet dry and comfortable. Irish Setter Men’s Waterproof Hunting Boot is a fine example of the state of the bootmaker’s art.
I sincerely feel that the best of all of us comes out in a disaster, with exception to a few. These few are the ones that this article does not or should focus on. Avoidance of perspective team members should be steered more by ethics, integrity and morality. I personally avoid thieves, liars and evil-hearted persons, and lastly the drama queens or snakes (team busters). Everyone else is trainable, deserving of a chance and usually becomes a viable team member in a short amount of time. But back to Powderkeg’s comment, “I can’t save the world, only my family.” This is another one that wasn’t mentioned in the article – The Save The World or Everyone Prepper.
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
