It did cross my mind until 5 years ago when my home province was struck with a 7.2 magnitude earthquake and had to experience almost all of those stuffs you listed above.
Fortunately the buildings in our town where left undamaged but the power plant supplying electricity to the whole province was badly damaged. Since the parts needed where mostly custom-made and are very expensive, they don't have any backup parts in case of emergencies like these (or so they said). Added with the cable lines in the whole province being messed up, it took almost 3 months to get the electricity back up again.
Anyway, many people here wants to experience living life away from modern stuffs and technologies we are now used to,, but truth be told it isn't that great. Having no access to the internet equals limited source of information which we badly needed at that time, no "comfy stuffs" like AC is just unbearable in a hot country. I could probably live without a phone or SMS but no. After having experienced all those things, it never once again crossed my mind to live away from modern life. I love living life in comfort. :)
I see your point. Thanks for the reply.
