The general reasoning is that while it doesn’t help with ocean acidification or a thousand knock on effects, and most certainly doesn’t ‘solve the problem’ as you put it, such measures would blunt most of the most deadly ones, especially for poorer nations that don’t have the resources to abandon coastlines, flood, and drought prone areas.
Especially since even if all artificial co2, methane, and nitrous oxide emissions snapped out of existence tomorrow we’d still see feedback warming for years to come, and centuries to return to where we are today, killing hundreds of millions of people in the meantime.
If they work effectively, which I am admittedly personally highly skeptical of, any of these geoengineering projects could save tens of millions of people for negligible cost long after we’ve hit net zero.
I am however also skeptical that it would significantly encourage companies to pollute more, as that necessitates you to expect them to pollute less if they think millions of people will die at some point in the distant future because of it, and I think basically any graph of fossil fuel useage after we all agreed that it was killing a shit ton of people and had to be eliminated in the 90s pretty well proves that not to be the case.
I also don’t think that needless death and destruction will modivate significant political action, see Covid, it just makes people suffer.
