The Fencing Act will require an upgrade...

every home will have a drone

You're going to use a drone to do rooftop inspections

I eagerly await the next tree hugging greenie looking for evidence of dirty dairying raping the environment or me buggering fetid swamps on my farm.  

No doubt the modern feral (or regional council inspector) will have a personal  drone for that over the farm fence leering and lurking.  And like any other noxious pest, a drone will be blasted out of the sky with 12g buckshot.

I see an opening for an entrepreneur,  a drone patrolling my perimeter fenceline using a GPS mapped run and capable of delivering the necessary fatal blow to other intruding drones 24x7.  The Fencing Act will require modernising.
