When I was involved in this, the real cost of capture, all things considered, was in the high thousands/ton. Climeworks, which is one of the companies trying to take this to a big scale, quotes it at 1,000EUR/ton. No one really talks about "carbon emitted while capturing carbon", though, as that would make the numbers MUCH worse.

So, I don't think $200/ton is feasible now. Even if that were the price, 7T/year is like 10% the GDP of the whole world. That means everyone, literally everybody in the planet, people and corps., have to put aside 10% of their income for this to happen. Impossible. I was selling 10k/year commitments to companies making hundreds of millions/year and they were like "nah, we'll think about it".
