> if every single person took every single action to reduce their carbon footprint they possibly could, the global economy would simply collapse

This is very hard to believe, and makes the reader believe you think economic systems and societies are a bunch of discrete and discontinuous processes. Their efforts, just by taking inertia into account and limited ability for people to change their behavior immediately would send signals progressively to businesses and governments, allowing a good chunk of the system to adapt over decades. A lot of businesses would definitely go bankrupt, but generally econ people are aware of that and think it's a natural process (Schumpeter isn't new).

What you I mostly see in econ circles is just standard pigouvian discourse I believe, nothing too scary: if externalities aren't priced, people have no "real time" incentive to change behavior.
