As this is more of "can we make carbon sequestering commercially viable, or at least less lossy", I'm less worried about that and would be more concerned about the global market for ethylene being "316.8 Million Tonnes in the year 2023"*, compared to the tens of gigatons of CO2 emissions — though on the plus side, I'm optimistic about removing
most of those emissions and this kind of thing is still fine for the last 10%.
As for "less lossy" even if it's not always a commercial winner alone: my guess would be there's always going to be an easier way to get CO2 than "from the air", unless you're on Venus or Mars: take tree (or coal), cut up, put chips in oven, set on fire. Much higher CO2 concentration than air, likely to make most things that need CO2 much easier.
