In my opinion; healing magic can only heal what is understood. In terms of the psychological damage, one cannot so simply say they understand the roots of the injury, and simply wipe them away.
The more limited application of healing potions and the like, while not needing to 'understand' the injury, are also not able to just be freely consumed with little wait between. The healing properties are likely easily overdosed and deadly. Much like actual medication can be.
Thus why Esuna and Leeches could not so easily wipe out a plague; it is yet understood. The art of the Conjurer/White Mage and the art of the Scholar put a lot of emphasis on understanding, and the balance of the arts you wield.
There is no doubt healing magic is potent, and it should be treated as such. If you wish to 'get around it' to make 'injuries have more merit', then you need to make such things grievous, or ill understood.
In the end, though, just play responsibly, and work things to your own needs.
TL;DR - Healing magic can heal what is understood by the wielder.
