Gypsum is recommended for two primary purposes. They are - To remove excess sodium (Na)
- To build soil calcium (Ca) levels when a pH change is not desired

You're forgetting another important reason to use Gypsum: To make the soil more friable; making it better drained & aerated, reducing crusting, erosion, and compaction and allowing better root penetration.
