Sure, no big deal to desalinate enough for a glass of water, but they are talking about a municipal supply of water. Imagine if you had to pay Fiji bottled water prices for tap water. $100 to shower or bathe. This is not a matter of scale, it is a physics problem (thermodynamics). It just takes a lot of energy to desalinate water Costs are crazy and someone has to pay.
