Billions of tons of carbon will need to be extracted from the atmosphere. But removing it will do no good as long as even more is released. 100kt/y is like breathing on somebody who is thirsty. Yes, there is moisture in your breath. No, it didn't help.

Creating a carbon tax such that emitting carbon costs as much as they spend extracting it, and then handing that over to extractors, could enable scaling up to the point where it could do some good.
