I think the problem with all these analyses is that yes, all models are wrong, but some are useful. We spent trillions and totally transformed our society in the 20th century, not really based on much sound economic analysis (and certainly not because it was the cheapest thing we could have done), because the economy serves human society and not the other way around. Of course it’s cheaper to do nothing about the externality of climate change, but it doesn’t do the economy or us any good to ignore it. And a climate model is just a discussion point about the uncertainty we’re introducing to our future prosperity - what might happen, how bad could it be?
