That doesn't help the Iranians' lives! Other than getting more money injection by increase of niceness-seeker tourism, hahah.

Joking, if it's like this and is not terribly linked to a religious dogma( which doesn't seem to be, more like a cultural thing), I'm sure there's a 'raison d'être'(I believe natural selection applies to not-directly-biology-linked entities such as societies). Maybe violent fights/discussions are more prevented thanks to Taroof? That's a wild guess ofc.
