Fresh water is not a finite resource. You can simply make more by taking sea water and pumping in energy. It's not cheap but it's doable.

In the short term (while you build your desalinators), and in local water-stressed regions, it very much is.

perhaps the most hackernews take in this thread.

desalination isn’t just expensive, it’s existentially costly in terms of energy consumption, and I don’t see any dyson spheres in production.

		With modern desalination facilities it costs literally on the order of cents per liter. It's an inconvenience at worst in the modern world. It costs approx 3kwh of energy to desalinate one cubic meter of water.
