If you think about it, 2nd law* is the most relevant one because, after all, CO2, being so stable, is one of homo sapiens "favourite" waste materials (partition function yada-yada)

How did plants evolve to use it as nutrients. Solar power. since humans don't need to make fuel from air these days, maybe all of that solar power should go into compute?

.. I'm not saying any laws are broken, just that there are much better (=more efficient, more promising) ways to reduce global warming, like

It already works now (no airquotes), except for DAC entrepreneurs who try to hoard attention without having paid their "attention dues" first.

*And the one humans like to ignore because there seems to be so much wiggle room
