Where is this notion of "you can do anything on your property" coming from? A similar one is also "it's my car, I'll do what I want with it", etc. But all modification to both your house anr your car have a big possibility of puttinf others in danger. If you mod your car in a dangerous way or screw up your house electrical wiring, other unrelated people may get hurt - you don't have the right to do that!
