Exactly, it is more the transition that is impossible rather than the end state. You can't tell people to give up international travel, visiting family members, eating non-local foods, air conditioning, and the overwhelming majority of society's leisure activities and replace it all with gardening. Maybe that is a desirable end result that would be healthier for both humanity and the planet, but there is no way to get there voluntarily. That is just asking people to give up too much.
