Other people just don't care. I know a Mojave desert community far to the east of LA where water delivery happens by truck. It's a very harsh and unforgiving environment, but I really liked it when I worked out there some years ago and have considered moving there because I like solitude and am comfortable with a very frugal/minimal lifestyle.

Last year I ran across an LA Times article about how people were making different life choices due to the pandemic, and and other factors - specifically moving from LA to this place. In contrast to locals who tend to build low houses and choose colors that blend with the desert landscape, these people were painting their houses bright white and, I kid you not, installing swimming pools.
