We can have nice things and also take care of the planet. If your suggested solution to climate change is that we all wear loincloths and live out in the trees, foraging for a paleo diet, then your suggestion is going to be immediately ignored by everyone. There's no point in even suggesting trying to return to pre-industrial times, especially since we very clearly do not need to. Climate change is a massive engineering and social problem, but somehow reverting to pre-industrial times is an order of magnitude harder on both fronts. And pointless.
