I agree, there is logic in this.
I also think that we need to take responsibility for our lives, for the lives of people close to us, and in general for everything that we can influence. Just ask yourself how independent you are in life, do you have your own house with wood heating, do you have your own source of water and food? Do you have the necessary skills for an independent life, for survival, for protection from marauders? Are you ready for hour X?
There is no point in being afraid of something, but you need to prepare, take responsibility for yourself and your loved ones. And it's not just about a plandemic, but also about future situations.
