The title is the best part, but here’s an angle I haven’t stressed much:

What people often overlook in the climate change policy debates is that the severe outcomes that occur in the computer simulations typically don’t kick in until many decades down the road. Even if governments “do nothing,” so long as they get out of the way and allow conventional economic development, the future generations dealing with climate change (and AI, and biological warfare, and killer asteroids, and all sorts of other problems we can’t even imagine) will be much richer than we are today.

For example, just throwing together some ballpark calculations (from here, here, and here), it’s a decent guess to say that in the year 2100, real global economic output will be more than seven times as high as it is today, while the world population might be a bit higher than 11 billion. So, if current estimates put real GDP per capita at around $17,000 per year, by the year 2100 each Earthling on average will enjoy a standard of living of more than $70,000 per year.

So let’s say disaster strikes and the global economy is cut in half by the year 2100 compared to what otherwise would have been the case without climate change. Even so, with our ballpark figures that still means per capita income will have more than doubled rather than quadrupling.
