Not really (in the insane part). "Minerals" are a commodity that can be removed with mining and have value that way, land surface area is where you can build things and have value that way, in California and elsewhere there are also water rights to water that you have access to on your land, whether it comes from a well, a spring, or a waterway passing through it. (water deriving its value for agriculture primarily) If someone said you can have this plot of land for $1M and all of the mineral rights too, or for $400,000 without the mineral rights, many buyers choose the latter, never intending to drill for oil, or frack, or mine for other minerals.
