I don't have a heck of a lot of lawn now, but I have land, to keep people back, out of my face. I don't want to look at a house outside of my front door. I look at the trees, the deer, the birds. I don't want to hear the kids bouncing the basketball, or the sirens. If I wanted those things, I would still live in town. Been there, done that. The last house I had, we had a 7 acre "lawn", I actually enjoyed mowing it. It looked like a park. There is nothing "wrong" with the way you all live in Europe, but there is nothing "wrong" with the way we live and think over here either.
