Almost all water is previously USED water. Whatever it was used for is
just temporary. Water, like energy cannot really be destroyed - it's just
being used somewhere.

As for water shortages, the fix is usually quite simple to describe: the
areas susceptible to drought should quit growing water-intensive foods.
They should import water-intensive food from areas where water is
abundant. For example, it makes no sense to grow rice in the Sudan.

Right; just as it makes little or no sense to grow cotton in Arizona.

*Cotton* in Arid-zona???!??

Umm, yeah. You get to schedule the rainfall, there is very little danger
of destruction by hail or other natural disasters. Yields are good and
growing season is near ideal -- cotton loves hot.

Well, yeah, cotton loves hot (can you say "Egypt"?), but what they say
about Arizona is it's a place so dry the trees follow the dogs around.
Growing cotton there just doesn't make a whole lot of sense.
