I really hope my generation can kill off the concept of a "lawn". Growing a mono-cultured weed in a desert just so that you can have a Saturday morning chore is utterly baffling to me.
Killing the entire concept seems to be a solution too big for the problem. There are plenty of places where lawns require zero additional irrigation.
it will not make a lick of difference and I like my kids to have someplace to play outside.
There’s a lot of room between a grass yard and a safe yard for children to play in
Most yards are just natural local grass. A relatively small number of people put in extra effort to make it a monoculture, but most just let it settle into whatever the local grass variety is, and then mow it periodically.
And in the desert, most people don't have grass lawns.
