I read up until about this point in the book, but frankly I stopped because I lost confidence that KSR had any idea what he was talking about when it came to central banks, and more broadly finance in general.

Maybe someone here can help me understand, what exactly is the point of "carbon quantitative easing" over a straightforward carbon exchange? Maybe the government buying and selling carbon allowances (out of thin air) on the exchange makes this "quantitative easing", but I would avoid implying it's monetary policy when it seems like it's clearly fiscal policy.

Even more confusing to me was how KSR's "carbon coin" plays into all this. It seems like dollars would work fine. Euros if you want. Introducing some new world currency just seems like it's throwing a huge wrench into an already controversial issue.

I think market-driven solutions to climate change are an exciting possibility, but I just didn't understand what he was going for here.
