The notion of leafblowing is also mindboggling to me... You don't need a leafblower to clean up your driveway, and leaves on a lawn will turn into soil.
My neighbour has a golf court style yard and constantly provides friendly suggestions how to better take care of my yard - with fruit trees and wild flowers. There are no mechanisms he could force his views around here, but boy would he love that.
More likely leaves on a lawn will destroy it and will create a dirt patch, at least this is what happens in PNW (Seattle & Portland). I have giant maple trees next to my house and I get 2 feet of leaves in my backyard every fall, if you don't remove them you get a breeding ground for rodents, you get mold and dirt everywhere (and clogged gutters, clogged street drains) and standing water. And it's not only leaves, I'm getting fir/cedar needles and maple seeds on my drive way, good luck removing it without a blower.
