"Completely sustainable" is a technically true but only for a fairly low (<20%) percentage of locations. It's just evaporative cooling, so it relies on a large water supply. It also increases local humidity significantly so it can make the outside environment even more uncomfortable much more quickly than normal air conditioning. It's also more expensive anywhere water isn't essentially free.
That said it's great in places like India and southeast Asia, where huge numbers of people live.

In Germany, where virtually no private home has AC, it can get really hot inside from June to September especially when houses are not that well isolated. But people just go on with it. In places like Texas or California, this is another story. But as you stated: probably it is hot enough for some kind of "persian style" cooling.
