And that's irrelevant if that other location is the ocean - which would be the case in over 66% of situations, as a general statistic.
(And it's also somewhat irrelevant if the lost rainfall would be in the open desert, because it would just be scattered onto sand and then re-evaporate.)
What you need is to compare the costs (and energy usage) of desalination to the cost and energy of this curtain contraption. I doubt it would be a mountain; it would just be a mega frame with lots of fabric. Maybe even with solar panels. Swaths of the land underneath could be a giant greenhouse or otherwise put to use as well.
