Yes, at that scale, the price of CO2 approaches zero, especially with the caveat that it shouldn't be reintroduced (as with carbonated beverages and pressurized machinery).
Carbon dioxide sequestration or transformation is the next step. Getting the first step to be economical is also nice.
CO2 injection is already done in many oil fields for enhanced oil recovery. People already know how to pump it down into the earth and track where it goes. Put a decent price on removing CO2 from the atmosphere and people will quickly figure out how to do it for a nice profit. Lots of old oil wells in west Texas also.
