A soft collapse? Sorry, not an option. The global collapse dynamic has no safety net where everyone keeps chickens and filters their rainwater while swapping seeds with friendly neighbours. It will be billions of people willing to do anything to get food and water that will be essentially unavailable.
This debate is no different than others that pluck out 3 or so system variables to be held out as keys to a better future. This is the same system blindness that characterises both intransigent BAU and ineffectual alternative movements. What's interesting here is the level of confidence that economic growth is intrinsically destructive so the only escape is to take down the global economy, effectively opting to end civilisation. I'd suggest it would be simpler to end our system blindness.
Where are we without sovereignty?
