The "DPS indoctrination" is the result of game design. There is no other avenue for a Healer Job to be useful when heals are not needed. You can certainly blame individuals for pushing DPS too far and fail to keep their party alive, but you can't blame the healer community as a whole for pushing the idea that maximizing DPS contribution is a virtue a healer should aspire to.

There is nothing else a healer can optimize around.

Optimizing heals leads to the same result as optimizing DPS: Minimizing overhealing, freeing GCDs, minimizing MP cost of survival. That leads to free time a healer can only employ in the only thing that is useful and available to them: Doing damage.
