It isn't because of scale. Producing CO2 emissions is easy, capturing it will require an equal amount of capturing capacity. Unless we invent something that can scale up to capture 100% of current emissions (or even just 10%), reducing CO2 emissions will remain more economically viable.

The other problem is of course that if we can capture co2, the producers will just ramp up production. Compare with electricity production; if production goes up, cost goes down, consumption increases (because cheaper) and they will have to ramp production up again.
