I think a certain level of preparedness is good. I have water for a couple of days, and a waterfilter, and dried food for a couple of months. (or closer to a year) I will be tired of all the lentils and rice after a while, but I will survive. The dogs have feed for several months, too.
As for water, we have had some scandals here lately that has given whole small societies e-coli, and people are asked to boil their water. In that kind of crisis it is good to have a stock of water atleast.
I have also firewood for a small fireplace, a small cooker and lights that are charged with solarpanels. And loads of candles. It happens often that some villages can be without electricity for up to 3 days, so it is just common sense to be prepping for that and even more serious tribulations.
