At the risk of sounding like an old fart, a point I've not seen raised is that older folks may remember a less comfy time and have some insight into the height from which we stand that modern kids lack.
My folks were products of the depression and dust bowl and world war. The marks of that time were plain in how I was raised. I was lucky enough to fall in the Selective Service gap between Nam and Desert Storm but my dad was in both Germany and Korea and cousins and older friends served and died in 'Nam. But even in middle America, let alone the working poor world where I came from, the '50 & '60s were just cruder and much more spartan than today, but at the time our moms and grams thought it was the lap of luxury if that makes a point.
Look around you, few electronics, nothing digital, virtually none of the things you see of plastic, stamped metal, pressed sawdust, or cheap imported origin were available then.

One thing I've noticed about doomers in general and peakers in particular is they seem to know more than average about the working of things. This too adds to the ability to imagine life at a lower level, although it often leads to a belief the "system" is perhaps more fragile than it might be in reality — hard for me to tell for sure as I suffer from that impression myself.
I'm a prepper since forever (at my granny's knee) when it was just called "putting by." I got into the habit young. Then with a family while working seasonal construction it became routine. Only later as sort of a hobby. Relatively few people under 40 will have seen their parents farming or ranching, canning, sewing, hunting, preserving, butchering doing more than piddly bolt-on mechanics/carpentry/plumbing/etc or any of a million things mine did from necessity and/or lifetime generational habit.
As for posting, I was dialing up BBSs back before today's digital natives were born, maybe before their parents. It isn't really a substitute for meat-world socializing, although early on here at PO there was a pretty cool esprit de corps. Frankly I don't find people that interesting generally, likely I'm not either so I take hours at a time to edit a post. Posting —especially long form as here has always been a way to learn and share what I've learned and even bounce ideas just to see if they are valid.
The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves -- in their separate, and individual capacities.
