You are probably correct about some seeing such events as "true freedom" which is a bit silly when you think about it why not just move to remote Alaska or really any remote area of any state and just live more or less off the land you can go do that right now if you
wanted to

.
That little fact makes me think that for many it is really more of a fantasy maybe it will happen but they must not truly want to live that way because you can live an of the grid lifestyle without having the world end.
Most of these types I think they have limited actual experience "roughing it" or with survival skills such things take actual experience you don't just go read a Boy Scout manual and then buy the materials and think that will do if you have no actual muscle memory with knots or have never tried to catch and clean game or truly raise crops or livestock you ca not expect to do very well when suddenly you are doing it to survive.
My dad went through survival training in the military at one point they had to capture and kill a hare just with basic tools it was not very easy and then they had to skin and clean the things
one guy he had his hare all ready for cleaning or so he thought when he went to start skinning it the thing started crying in pain he had not killed it the guy had never killed a living thing before and was held aback by the event and one of the instructors yelled at him to finish the hare off or go hungry the point was when you have nothing you have to take what ou can get even if you do not like it.
These people seem to think that having some supplies and a some guns and bullets and they will survive anything when the most important tool/weapon is your brain.
The value of information is also key as was said earlier so radios are important with a short term disaster in particular long term you would need a HAM radio or know someone that dose a HAM would be very useful long term because you can talk to people hundreds even thousands of miles away very useful for finding out what is going on.
There is a way to protect electronics from getting fried as well a Faraday cage the military uses them supposedly you can make one though how well it would work is anyone's guess you will also find them at power plants and power generation stations.
