While sand is used in concrete, desert sand is useless for any construction use because erosion by being blown around by wind rounds off the grains. As the author of the linked article puts it: "Imagine trying to make a building with golf balls."

Of course, when something picks up some value, organized crime will opportunistically move in.
Out of mild curiosity... how hard would it be to collect desert sand, melt and mold it into lumps, then crush it back into sand again?

Not hard, just incredibly energy intensive. (So way harder than mining sand elsewhere.)
