The problem is that we're well past the point where "carbon-neutral" is good enough. We not only need to stop causing additional harm, we need to figure out ways to undo at least some of the harm we've already done. Given the limited time frame, there's simply not enough time left to "upgrade" all production to be carbon-negative (or at least carbon-neutral). Even if we could magically swap out all factories and infrastructure, we would still be overproducing and depleting scarce resources. Plus of course thermodynamics are working against us: burning oil is easy. Extracting carbon from the air and refining it to create a usable resource on the other hand is extremely difficult and energy intensive. Trying to ramp up recycling instead of harvesting raw materials would create a massive additional need for energy, meaning we would not only have to shift to renewables but also do so while ramping up the energy production. Plus of course nuclear power still requires mining for raw materials and building the batteries needed to store all the variable power from wind, solar etc would require even more (and rarer) raw materials. Basically we're talking a massive overhaul with very little financial benefit (and often quite the opposite) to those owning "the means of production". The costs of not doing it may be incalculable but the costs of doing it are far more direct and immediate. Capitalism doesn't optimise for long-term cost reduction. An individual capitalist may prefer long-term survival over short-term profits but the economic system as a whole doesn't work that way and an individual "taking the risk" of investing will be punished (i.e. lose market share, go bankrupt or be bought out) if the market outperforms them in the meantime. That's why I'm saying the problem is capitalism: it's not some Marxist-Leninist navel-gazing. The very way capitalism works makes it impossible for those with the power to do so (i.e. "the market") to do anything about climate change. It's one big prisoner's dilemma. The only way to win this would be either for a significant majority of wealthy people to cooperate and invest everything they have, or for a single individual to control the majority of the market and force the decision (which of course doesn't work if more than one person does this) -- guess which strategy is more appealing.
