As I keep saying, I am not frightened (never mind panicking).
I have house insurance, in case the place catches fire, or other unspecified problems crop up, and a first aid kit in case of accident. This is more of the same, as I see it. There are always those who don't look ahead, and end up starting JustGiving pleas and so on to compensate. Deliberately avoiding storing a few bottles of water etc is the same way of thinking - 'it probably won't happen, and someone will sort me out if it does'
People are not digging bunkers or converting their garages to warehouses - it's a box in a spare bedroom with things that will help to get us through a few days without power or access to the things we are used to having on hand (eg shops). Nothing to do with a zombie apocalypse or a nuclear winter, but knowing we can be a bit more comfortable than otherwise if the power goes off for whatever reason.
I believe that parts of the UK had weather-related power cuts last night, for instance. A lantern to see in the dark, blankets for when the heating goes off, and water to drink is a good start, surely?
I give up now. It seems that we are in two camps - those who want to be prepared and those who don't. I doubt, after all the posts and threads discussing this, that one camp will ever persuade the other (until after a long power cut, at least
)
