I think Xorkoth's power outage story captures why we shouldn't be to eager to abandon what we have. You don't know the value of something, really know the value of it, until it's gone.
Sure, society has its issues, but the idea that we need to return to nature.. we are nature. We are not doing this, none of us are. What's unfolding on this planet is as natural as anything else, we shouldn't be so eager to throw it all away, and we don't even know if this is all part of some wider design or engineering way beyond our understanding. Personally I see society as a launching pad for civilization - many men will die in the construction of the vessel of civilization, and the environment too will take a hit, but perhaps this is merely the energy requirement necessary to furnish the vehicle and get it into orbit so to speak.
There's this grass is greener refrain I often see posted, indeed I have uttered it in my youth too, that if only I and a small band of similar people could just find ourselves away from the clutches of modern living degeneracy then we could do it right, get it right and live a balanced life. Of course there's always the caveat that this noble tribe shall live 99% naturally but still get to enjoy the 1% benefits that society has developed, such as steel tools for example. Naturally this fact is always overlooked and never really contemplated seriously - unless you go 100% you haven't left at all, you are still reliant on society and are no different from the millionaire celebs who live in 100% eco houses and think they're saving the planet. Anyway, so your tribe decides that actually it does need steel tools but doesn't want to interact with society to obtain it. OK. So where is the knowledge coming from, the manpower, the time and facilities for you to mine, refine, smelt and cast the steel, just so you can have basic tools? You need to expand your numbers to get to that point, which begins the inevitable progression towards society again.. because as the numbers grow so to do wider social forces within the group that require mitigation and sublimation. Religion will sooner or later come back into the picture. And so on.
I quite like using the example of Eric Cartman in Southpark when he buys a theme park for £1,000,000, just for himself because he's a selfish asshole. He very quickly runs into the issue of realizing he needs a security guard to keep everyone out. Costs money. OK, need to let in 2 people to cover the security mans salary. OK, rides break down, need maintenance guy, need to let in 2 more to fund that. And so on, until the theme park has got right back to where it was originally. It's a twisted and divergent contemporary example, but I hope you can see the parallels in it. Once the ball is rolling you can't stop it and it's pointless to fight it. Cartman inevitably fails because his ideal was not compatible with the wider natural/social forces at play.
Some say we need to go backwards to mud hut living again. Some say we need to leap forwards to transhumanism, or planet colonization. Look what happened when electricity burst on the world at the beginning of the 20th century. It alleviated a lot of suffering and drudgery, but it also accelerated the degenerative influences in our society - our 24hr world couldn't exist by gas or candle lighting. Overall my point is that it doesn't matter if we go back to mud hut living or forwards into transhumanism; until we sit down, shut up, and figure out what the hell we are, who we are, then we are doomed to cycles of endless suffering. I wish I could put it more eloquently but I firmly believe we will be doomed to repeat the same mistakes regardless of technological level - we have to understand the forces at play in ourselves and the group first.
Ironically I think some attempt has been made in this regard down through the ages by visionaries and intuitive individuals, and their insight has been coded into the major religious texts as personal guidance on moral conduct in order to mitigate and sublimate some of these individual and wider social forces we can't put our finger on. To that end I think we've made a real mistake in our modern wisdom by becoming too materially focused through science, and believing we can simply decide through democratic voting what constitutes these invisible social forces; you only need to look to what feminism has done to marriage and the damage in relations between the sexes to see we're in real trouble as a society now.
