I have the tendency to stock up on items that may not be available in the future. Such as odd colored pens (you know, the ones other than the standard red, green, blue, and black). Such as polymer erasers. Also, it never hurt to stock up on paper and stationery items, especially if I know there may come a time where I need such items and they might not always be available.
These days, it is more in line with the advent of communism. I cannot prepare for communism itself--that is impossible. But, I can get ready for some of the shortages and disruptions that precede it. I have plenty of NiMH batteries and chargers for rolling blackouts. I also have quite a few high quality flashlights--Fenix is the brand that gives me the best tradeoff for lumens and run time (and has modes around 6 lumens, which is perfect for finding my way around a store that abruptly goes pitch dark without helping others that do not deserve it). I have plenty of silver, just in case the dollar becomes toilet paper. I buy most of my clothing from L.L. Bean, which is way better and meaning that every shirt from there is worth 5 or 6 from the junk mart. I buy enough supplements to last 2 years, because I am afraid they will become illegal without warning.
In addition, I have an emergency bag that has survival items. I got a multi-tool system, a hatchet, a small saw, emergency shovel system, fire starter materials, and paracord. I know this could be money I didn't need to spend, but it is better to have these items and not need them than need them and not have them.
Of course, these days food is a primary issue. No one has ever died just from lack of toilet paper. Maybe it is a big embarrassment, maybe it can stink. But, food--I think more will die from the coming famine than from coronavirus. I am stocking up, gradually, on items like canned chicken, vegetables, cereal, grains, peanut butter, and the like. Instead of relying on those emergency rations that usually taste terrible or government handouts that come with RFID chip requirements, I rely on my local supermarket. And no, I will not go to that dump called walmart. I have been getting plenty of decent items at a highly ranked supermarket, and I would rather get more expensive and better quality items to save the cheaper items for those who have lost their job. Yes, this means I have as much farro and quinoa as these others have rice and legumes. It also means the rice and legumes are available for those who are in need, without work and whose stimulus check has run out or hasn't come yet and will need to pay their rent for three months in June or July.
