That seems to be deliberately obtuse.
It is more like being a firefighter and being opposed to airlifting icebergs to drop on fires.
Sure, you'll get water eventually and you might even extinguish a fire; but how long does it take to organise and deliver, what can go wrong in the process, what are the consequences of a mistake like dropping it prematurely, and why are we ignoring the honking great big cheap river right next to the house fire we are fighting?
so only do things that yield results fast.
The time to build nuclear reactors is a completely pointless argument because humanity is going to need low CO2 power forever. Without nuclear wind and solar will ALWAYS require gas turbines for backup.
