Were they talking there about the Marxwell's demon?
Anyway, CO2 capture, by itself, is not the whole solution, but it should be part of it. There is an unbalance between the energy that comes in and the one that goes out. so things heats up (among other negative consequences, like i.e. ocean acidification). You won't solve the whole problem without addressing that eventually, so some way of carbon capture, going through the use of energy or something else, should be in the map.
And the complementary part of that is stop adding new (or, in other way to see it, very old, but that was stored away) carbon to the system. Even with the very worrying signs of the global climate going haywire with the corresponding loses of lives and money we keep adding each year even more fossil carbon than the previous one, no matter how much token energy generation is announced to be done by other means.
It may be expensive, or require technologies that we don't have yet, or compromises on what to lose, or whatever, but it is a problem that if left by its own means will eventually make the planet unlivable for us in a way or another. And that will turn all the saved money into something meaningless.
