I know if I lived out here with all of this space, I would say these exact words to people just driving by. I would always yell at people and maybe even ring a cowbell or a gong. I would be That neighbor who is so bitter. I'd even raise a few kangaroos just so I could send them towards intruders to box their little hands. I would even fashion boxing gloves for them to make it authentic. I'd even encourage my service kangaroos to hop after muggles on command. "Sick 'em, Capone! Get 'em, Mack the Knife!" It would discourage unwanted visitors like vacuum salespeople, kids selling wrapping paper, my own kids.
