I think this wasn't about compromised air quality indoors. Rather general level of CO2 in the atmosphere. What help are ventilation systems then? You'd need to have submarine scrubbers in place to do something about it, and/or cans of liquid oxygen.

I think their point was that increasing CO2 in atmosphere makes it more difficult to keep indoor levels acceptable.

First, if you start from 600pm instead of 300, you reach 1000 ppm faster. Adding to the insult, it is much more difficult to ventilate the excess CO2 away, if the air you use to ventilate contains in itself already 600ppm instead of 300ppm.

Indoor air usually has significantly elevated CO2 levels compared to outdoor air.

More ventilation cannot push the levels below the levels of outdoor air, but it can get them close.

Their argument that assuming today's already inadequate ventilation systems don't change, more outdoor CO2 = more indoor CO2, pushing it above some arbitrary threshold (which is far above predicted outdoor CO2 levels).
