Absolutely agree. There's a lot that could be done to reduce CO2 and I also saw my old man's ex build a prototype CO2 capture system using carbon as catalyst all the way back in early 2000s. We've moved on a lot from there with regards to this but point still stands, is it a good idea? I'm somewhat skeptical. Did you see the recent research paper on CO2 greenhouse effect saturation limit? Makes for interesting thoughts. If the greenhouse effect input of CO2 saturates below current levels, then there is literally no way that increasing CO2 concentrations in the atmosphere actually do anything at all other than nourish plants. That might explain why the planet was ok with CO2 levels hundreds of time higher than current concentrations. Obviously, that would then suggest that we should be happy to watch concentrations increase, preferably to a plant optimum which would help for trying to restore damaged ecosystems and regenerate soils, as well as increasing food supplies. That being the case, optimal range is 800-1200ppm which is 2-3x current levels. Hard to say with all the obfuscation but it could be we should be considering giving out fines to people doing sequestration to pay for the damage they are potentially causing???
