Energy is not the only cost. There are also massive material costs building the carbon capture infrastructure. A reasonable estimate for the scale required is the existing fossile fuel infrastructure. That is, direct air carbon capture means investing an amount on the order of the value of the existing fossile fuel infrastructure to spend energy to achieve nothing of value (except offsetting the damage we caused by not switching to renewables earlier). It's a complete nonstarter. Only a vehicle used by the fossile industry to delay the transition.
