Lots of dogs like pulling laundry off the line, my first dog did it for ages until we blocked off her access to the area. Mostly did it when our dumbass housemate left his socks on the line for too long but was worse then that at one stage.
Having your backyard divided means they won't worry so much if the dog digs up spots and it can be puppy proofed ensuring the dogs safety (and anything in the backyard you don't want chewed) while it is young and apt to chew on things it shouldn't (don't get me started on the phone calls we get about puppies dying from being left unconfined in a backyard). Also means that if the kids want to go out and play and you can't supervise the dog can be separated for safety reasons (the kids and the dogs).
Kennels are good if the dog will be spending working hours outside alone.
Personally I believe it is fantastic foresight and pre planning. I would do the same thing.
