If you look at the chemical reaction of a hydrocarbon and then what CO2 sequestration is you’ll see that it’s still within the laws of thermodynamics. You’d potentially have a thermodynamics problem if you were trying to remake synthetic fuel from the air and hydrogen. And even if you’re doing that - there’s still an argument that it’s better to recycle the carbon than to continue to dig it out of the ground. You then talk about trees (which aren’t free from the laws of thermodynamics). The process of a tree for fixing carbon is not efficient, typically less than 1%. See https://en.m.wikipedia.org/wiki/Photosynthetic_efficiency https://en.m.wikipedia.org/wiki/Photosynthetic_efficiency And that’s before you get to the step of sequestering the carbon locked up in the plants.
