I think of it the other way around: if you are not into prepping, it is very convenient if you don’t have to refresh your supply frequently. You might forget about it, or not get around to do it, and when you actually need the stuff it has expired. I wouldn’t buy special, expensive survival stuff, but if you’re at the supermarket, picking your stash by expiry date seems like a good idea.
It’s also very convenient to label everything with its expiry date, using a permanent marker to draw it on the top, so you can check everything without taking it out of storage.
As I see it, water is the single most important item, and the rest is kind of optional? At least if you do not have kids? Three days without food may be a major inconvenience, but it won’t kill you. Sadly, storing food does not even work for me. I was seriously obese and lost more than 30 kg over the last few years, mainly by restricting myself on the side of grocery shopping. So when I start hoarding canned goods, they simply do not last.
What I strongly disagree with is the endorsement of the online password storage service. Online in somebody’s cloud is the exact place where you do NOT want your passwords to be stored. I think by now we can tell that everybody gets hacked at some point.
