I mean, the reality is that the lions share of water in all the places listed in the graph above goes to agriculture. And a lot of agricultural water is lost to evaporation. In Iran, for example, they are currently suffering a water crisis - but a big part of their problem is that the government mandates that X percent of all food sold in the country must be grown in the country.
Desalinization is nice and all, but there are much better and easier solutions to these problems, like making water cost more for farmers so they invest in tech to stop letting it evaporate or grow less water intensive crops, or importing more food instead of growing it locally.
