> People are not going to like things that make them stop eating meats, whether it's governement buying out producers, a carbon tax, a carbon quota, whatever.

I think the point of the book is that when the consequences are serious enough, it pushes significant social and behavioral change that people would not consider or accept otherwise. It's hard for us to imagine how society could actually change so drastically, but when people have been through a crisis of immense proportions, they think differently. India completely transforming its governance structure seems implausible but only because we haven't experienced 20M people dying at once from a preventable cause. These kind of events are triggers for social revolutions. We've seen this in history.
