Except there are limits which the demand, for the most part, can't overcome.

All of these things are energy intensive, aren't they? So as energy becomes more expensive, so do they. Demand never gets quite so high that it's worth it to pay for this, because the price is always rising. There's another alternative in such situations... "just don't buy carbon offsets". The PR hit's cheaper after all.
