The observation I'm making is that we know what the bounded risks are. We don't know what the lower bounds (or upper bounds) might do. We've planted lots of vegetation that depends on the growth of CO2 levels year after year (to some degree). It's not clear to me that if it gets too low that would be a good thing.

By the way, I'm not arguing that we shouldn't decrease the CO2 levels. We should. I'm trying to have a nuanced and interesting discussion about a very complex phenomena.

Each of those problems you brought up can also be mitigated with proper engineering as well.

Take for example how Israel effectively solved the drought problem. Now that's an exceptional case and it wouldn't be logistically feasible to expect every nation to dedicate so much of their GDP to such problems. I'm just trying to suggest there are other variables at play, besides moving CO2 levels up and down like a thermometer.
