If you are talking about eliminating carbon you are currently producing this doesn't matter at all. If you deploy 6GW of solar in a year, you eliminate as much carbon as a 1GW reactor would, only it would take you 15 years of further carbon emissions to get there. You talked about hidden costs of removing carbon, and this is a good example of something that you will need to remove.
And that's the situation we are in. The discussion changes once you saturate the market with solar but even advanced economies are far away from that and the world as whole especially.
