Why should you be guaranteed water if you live in CA? It’s an arid ecosystem that naturally has fires (chapparal) and low rainfall. It can only support so much life. Just because there are great views and great climate, the fatal flaw is lack of fresh water.
Just about every region requires some human intervention for comfortable living. Would you say the “fatal flaw” of living in CO is the lack of heat? Or the lack of AC in Texas?
