Genuine question, is it a good start? When does become not a gimmick? At 0.5g/km, 5g/km or 100g/km?

We need to optimize for "tonnes of CO2 scrubbed per dollar". This cost includes capital cost, and energy cost.

Because location doesn't matter, putting lots of small battery-powered mobile units is always going to lose to a large fixed industrial unit with an industrial-scale energy supply. Probably orders of magnitude worse on both CAPEX and OPEX.

Who is going to be paying for "large fixed industrial unit with an industrial-scale energy supply"?

No, we need to look at externalities and real world long term side effects.

The "per dollar" part is why we're in the current situation in the first place

No, because it doesn't scale, and its dramatically worse than a lot of other approaches, which range from 'also don't scale' to 'somewhat scale'.
