Not taking a cheap shot at the author, but wouldn’t the author fall into 1 or 2 of these categories? I think the human character of every individual harbors a little bit of all or several of these. Most, if not 100% of anyone prepping has in their specific individual plan – their family members. Each family member brings their own set of considerations (assets & liabilities) to the table. Are we to avoid/cast out these family members due to their nonconforming attributes? This eludes me to one of the categories you left out – The resistant/reluctant prepper. Because if you have a family there’s a strong chance you will have one of these, but they too come around in time.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
