If you want to prove you can live without all the trappings of society, go live in the wilderness. Bears, wolves, cougars, and any other wild animals, are infinitely less nasty and callous than human beings can be.
There isn't anything wrong with knowing you can live without A/C or some of the other things humanity has thought up. But doing it just to be doing it is kind of silly. Hell, get a plane ticket to India, or Columbia. Many do without fancy technology all the time.
