Actually I know quite a few people who do pay for air.
Every time I go scuba diving there's a whole bunch of us who pay to get the same air we could breathe for free, squeezed into a little metal cylinder so that it is much more useful when we're underwater.
Bit like having all this information collected in one place for easy reading on the train...:-)
