There are about 2.2 teratonnes of CO2 in the atmosphere. There should be about 1.5 Tt. That's ~700 billion tonnes of CO2 to remove, or about $25tn at your quoted price. Not impossible, but certainly not cheap.

At that scale, the price per ton would probably drop by a factor of 5-10 or more, so it looks quite doable.
