California is building desalination plants, for example [1]. However, these are expensive to construct and energy-intensive.
It's definitely worth the expense to ensure that people will have access to water, even in a future with intensifying droughts.
But is it worth it to ensure that people's lawns have access to water? Probably not. Especially when there are plenty of landscaping options that have much lower water requirements than a lawn.
A "growth mindset" generally refers to growing the amount of economic value produced - not the amount of resources consumed. Often, such growth can come as a result of technological improvements that increase efficiency. For example, more fuel-efficient aircraft allow airlines to fly more passenger-miles with reduced fuel consumption. Water conservation technologies - including some things, like xeriscaping, that you might not immediately recognize as technologies - are in the same category.
