Also, the authot mention sharing power from his newly purchased generator but doesn't seem to take account of mutualization of resources and solidarity.

Peopke can talk in a neighbprhiod and plan accordingly. Not everyone need a power generator, more than one family can cook from the same gas stove, etc etc

Even when total devastation happen, the radius tend to be limited and unless you live in a small island you can always find food/water and medical supply within a day of walking/cycling from the epicenter if no one is injured. When the DANA brought devastation in an area around Valencia in Spain, people would tak their bike from the main city to bring essential medical supplies to people living in places that weren't drivable too. So sure I always keep several liters of water and a few days worth of non perishable food at home, as well as a portable gas stove and a water filter I bought for hiking trips, but I would have no issue relocating me and my family for a while if needed. Adults and teenagers can easily carry 50kg worth of stuff with something as simple as a bicycle they push by hand, like people in congo do with much more capable chukudus. Electricity would be the least of my concerns.
