I'd say the most effective way for me to scrub a lot of CO2 out of the air is to burn a lot of fossil fuels, and then scrub 80-90% of it (or however efficient scrubbers are). Seems like the wrong incentive?

I feel this is somewhat similar to the story with trees. See e.g. https://www.bloomberg.com/news/newsletters/2021-04-21/money-... and https://www.theguardian.com/environment/2021/apr/11/negotiat... .
