We'll actually HAVE to do it at one point but yeah, it will take a good 30-50% of the world's energy budget for decades to centuries to do so.
However, until we're on 100% nuclear / renewable, you're just generating 100 carbon for every 30 you capture. That's where the stupidity lies. Even if you use renewable energy to power your capture plant, it still be more efficient to just route that energy directly into the grid where it would then avoid someone else having to generate the carbon to use the energy.
