I think you missed the part where extracting CO2 costs huge amounts of energy, and converting it back to oxygen to capture pure carbon costs the exact same amount of energy as you got when you burned it in the same place. Add losses due to heat etc, and basically if you want to dial back the clock for CO2 levels, and given that no other extra CO2 is being emitted anymore, you’d need to spend about twice the energy the world generated. Want to dial CO2 back how it was 10 years ago? That’ll cost you about twice amount of energy that the world has spent over the past ten years by burning fossil fuels.
And that is on top of the normal world consumption of energy, and that is also assuming that all CO2 emissions have stopped. That is also ignoring energy costs for storing the carbon as well

So yeah, good luck with that.
Yeah, we are going to have to do that to unterraform our planet.
Might as well harvest sunlight to do it.
