They also need to recognize that asthetics is not the only factor. You can't kick a soccer ball on a lawn covered with shrubbery. While a natural landscape can be fun for kids to play in, it's not very versatile when you just want space to roll around and have fun with kids. But sure, if you never go outside and never set foot on your lawn, then a maintenance free lawn is fine. All the rednecks in trailer homes where I come from think so too. You could even store your older vehicles that no longer run on the lawn in case you need parts later.
