You know grass is extremely important for biodiversity right?

Having only one species in your yard is not biodiversity.
Just because the lawn is monocrop doesn't mean your bushes, flowers, trees, birds, bees, other bugs don't thrive on that environment. If not maintained, all you will have are invasive insects and weeds.
Just look at the soil in an unmaintained yard vs one with a good lawn. Good soil brings biodiversity.
You've yet to explain your position.
An unmaintained yard is a strawman argument.
If you don't understand my stance, as explained in detail, what parts are you confused by?
