Physics and thermodynamics don't actually use $ costs in their equations... e$ !== mc2

The costs you are referring to are in energy. It's entirely possible that the $ cost to put it back into the ground are cheaper than to get it out.

Hmm, mostly depends on where you put it. Putting it into ocean would probably be add hard as getting it out of there.

Except here we can put it into storage in a more convenient place.

The real problem is that we do not have enough energy to run this yet. A bunch of nuclear plants would solve it but these come with political baggage. Unfortunately CO2 recovery is very local.
