That's a nice example of how it can turn out, but it's not always like that. Land is abundant, but in many places housing can't be built. Water is abundant, but Nestle still makes a fortune selling it. If someone could find a way to sell air, they'd apply for a government sponsored monopoly (a patent) on it, and lobby government agencies to recommend it over the natural air.

Far too many people make their fortunes gatekeeping access to resources.
