Even without lawns people will use leaf blowers to blow leaves, off their driveways or xeriscapes or whatever. So we should ban gas powered leaf blowers regardless.
Quite frankly, I think such housing areas look far, far better than your typical grassy suburbia.
I do agree that houses with large lawns and zero food crops are just... wasteful. I rent so I am limited to what I could do, otherwise I would just till my lawn and make almost the entire thing into garden beds.
I dislike seeing those houses that have what amount to prairies and on that grass you see just a few horses or whatever. Such a waste of arable land.
