Motivated reasoning. Cheap energy is extremely attractive, so seemingly obvious downsides can be swept under the rug.
People laugh at Preppers and call them crazy for taking prudent preparedness steps as insurance against future risks. It's a very human thing to do.
During the early days of COVID, some people started coming around to preppers being not-so-crazy-after-all, which lasted for precisely a few months before the toilet paper returned and preparedness being an acceptable idea left mainstream thought.

I think most of the time people are laughing at preppers on TV. Having an emergency radio, a gun, extra water storage, a back-up generator, etc. - I haven't experience many people who laugh at that, though certainly I imagine someone exists who does. The government publishes info on emergency disaster preparedness kits and other things too.
