Collectively, we spend an awful lot of resources on air. Clearly it must be of some value, otherwise we wouldn't bother. Unless it's a scam.

Sure, we're not being metered and charged by volume of air used. But someone, somewhere, is spending money to make sure it's suitable for breathing. And it's a pretty penny too.

> This is like saying you could charge for air.

Is the value of air $0 to you?

The value and the cost are not the same.
