I wonder if there is a special advantage for geoenginnering solutions like carbon sequestration where instead of perturbing a complex system and using technology to individually manage all the negative consequences, we use technology directly on the variable we are influencing. It frees us from calculating all the consequences.

Not really. I bet carbon sequestration kills a few people one of these days. What if someone pumps a lot of CO2 into a mine, and it ruptures into a small valley? CO2 is denser than air. Everything has consequences.
