Removing CO2 from atmosphere is still much, much more expensive than alternatives. People just don't seem to understand the vastness of our atmosphere and the scale of operations that would be needed for this.
Our atmosphere weighs ~5 quadrillion (5x10^15) tonnes. We are talking about an apparatus that can suck that amount of gas and process it to remove CO2 that is already very dilute.
