Serious? That's a huge claim. yet, so many people do live this "quieter" life. I am striving to live that life. There is quite a growing community (at least in British Columbia) of people concerned with things like food security and climate change.
Ever since I was young, I was disgusted by the City. Yes, this is not a popular view, but I am in no way choosing to live "a more basic quieter life against our natural instincts." The city was never meant for me.
Though, I'm not really sure what movements you are referring to? Do they include those that suggest consuming less? Or are there some movements somewhere suggesting you start living by candle light?
Sorry, if this comment is off-topic from the article, but it seems wildly bold for you to claim that a way of life is against natural instincts. I strive to live a life combining the joy, satisfaction and security of producing my own food, and living with the land as well as benefiting and perhaps contributing to advancements (particularly with water and power management).
