Then not wanting to waste the various stocked up food in the fridge/freezer. You could forgo this and consider it lost, but since you're already trying to tackle the general problem, it adds to the motive.
Other possible stressors that don't seem to be in play here are needing heat in the winter or needing cooling in the summer. Personally I'd rather not freeze to death, or even have to huddle under blankets hoping for someone else to rescue me. And an outage not in the winter is a great time to practice.
In general, problems compound so when faced with such a situation that lops off a huge amount of normalcy, the understandable instinct is to try to right the situation lest you fall even further. Camping is great and all, but you're still relying on the option to come back to full amenities and pay off the accumulated debt.
