There is nowhere close to a research consensus agreeing with you - this is a very open question still. There are certainly a lot more reasons to be skeptical of a direct-air-capture industrial solution scaling though. Any source that does not look at the benefits of a circular economy of kelp farming (producing more fuel and plastic to build the next batch), as well as upwelling tech (bringing nitrogen from the deep sea to the surface) is missing key facets too. It's very plausible large swaths of the ocean with little life currently could be turned into viable kelp farms (great for fish and life) which pay for themselves sinking CO2 by selling excess fuel and plastic. Demand is more likely to be a problem than production. If only we could think of some useful things to do with endless dirt cheap biodegradeable plastic. HMMM Kelp and biological sources of CO2 drawdown (bamboo on land) are much more cost efficient, environmental and scalable than any industrial drawdown process currently known.
