Of course, but they have lived that way all their life, most country people do not live that way and you know it. And by the way they cheat, a lot. They won't dial a phone but if you dial it and hand it to them they will. They also drive tractors to town instead of horses to church on Sunday.
I was not trying to sew discourse, just pointing out that 99% of people could not live today without electricity because we have chosen to live this way. Amish have chosen not to live the way we do and could survive.
Have you ever sawed ice from the river in the winter and buried it in straw so you could keep meat fresh for a day or two without smoking or canning it? I have lived in hard times when a block of ice was more than the budget could stand, most people today would have no clue how to do anything to survive without electricity, gasoline or any form of power. Have you ever eaten a blackbird, meadowlark ? Killed and eaten a cotton tail, opossum or tried to eat a jack rabbit? I have and I don't want to try it again at my age, but I suspect I could survive for a while, but not without multiple medicines that I now take daily.
Without power all those things disappear and they won't come back easily. That is why may people have worried about our integrated electricity network could be easily taken out, maybe they are right maybe not but they are not wrong about the destruction that would happen if we lost it. Most predict that 90% or more would die.
ps I lived in an Amish neighborhood for years.
