This has all been discussed before but...

For the vast majority of applications, it's cheaper to not emit in the first place, or capture the emissions during whatever process releases it, than capturing from the air.

However, just the greenhouse gases that are already in the atmosphere are more than sufficient to cause unacceptable climate impacts, and it will take centuries to get back the pre-industrial climate. As such, we will almost certainly want to artificially remove CO2 from the atmosphere - go "net negative" rather than "net zero".

We need to change society not only to stop increasing the emissions (because that's what's happening now), but dramatically reduce them. Also we need to change society to handle the impact of climate change as well as possible (but for sure climate will make our life more difficult).

Nothing is worth doing if we don't dramatically reduce our emissions. Whoever says "no but you see, I don't have to cut my emissions because I am working on CO2 removal" is lying to themselves.
