Hmm, still not sure I agree. Reducing emissions to close to 0 is definitely very important but it seems probable that we'll reach a steady state where some niche sources of carbon still persist, and are accompanied by corresponding capture. Some niche sources are just unbelievably hard to decarbonise

If in 20 years 1% of our emissions remain but they are accompanied by capture (with a multiplier to account for inefficiencies in capture) then that would be ok by me.

(You'd still want the extra carbon removal to reverse the warming caused by past emissions ofc)
