There are many, many realistic situatiations, where you might end up without power, outside, or even locked at home (like going abroad when the neighbouring country is in a "green" covid state, and your government changing their mind overnight, how they decide 'colors', and classifing it as "red", and you need to quarantene for 14 days). Plus all the "i have the flu, I don't want to go to the supermarket today" situations.
Having some supplies at home (canned food, pasta, etc.) and some extra other stuff, a barbecue or something to cook stuff in, and an extra pair of socks & a shirt in your car is a very smart thing to do. Our grandmothers, living in villages had full cellars of food not that long ago, with sacks of flour, salt, and knowledge how to bake bread, and it was a totally normal thing to do and have (and people outside of big cities still do that).
And reality TV? Show a nutter, thinking about rapture, with a cellar full of some dry freezed crap, some 5 year food supply pack on a couple of pallets, still unopened, with an expiration date two years in the future, a huge amount of guns and ammo, and a "tactical" toilet bag, with a tacital, camo colored emergency toilet paper cutter, ...just in case.
This makes preppers look stupid, their prep cases look unrealistic, people having half a slice of toast and a jar of mouldy mustard as only food items in their house and people literally starving when their delivery driver cancells their order due to icy roads.
