I'm not trying to stop you just point out you shouldn't worry yourself too much about these things because they're unrealistic in the short term.
I don't worry too much about it. I just think it's sensible to worry about it enough to the point where you have some idea how to survive if it happens. The signs are there that our financial system is under immense pressure. USA will go to war with anyone to protect the dollar. There is certainly the potential for hard times in the future. I just don't really want to be thinking "I wish I'd learned how to filter water" as I shit a stream of brown liquid.

It doesn't hurt to learn stuff, or discuss what you think you know with people who know better.
