I am afraid extending personal "moral rights" to the domain of property damage is a risky avenue to pursue. Who defines what's moral? I also don't agree with that the failure of enforcement by the society automatically grants anybody a moral right to break the law. What about all uncaught murderers? Actually, it is interesting we transverse to physical damage here. I wouldn't equate seeing outdoor ads to receiving bodily harm, to a theft of a piece of "consciousness" or attention - eh, maybe...

I don't know much about philosophy, but what if we can assume that legal rights end and moral rights begin only when we deal with someone's natural rights, is this tenable? If we take the Declaration of Independence as a starting point, as long as there is no danger to our life, liberty and pursuit of happiness, we should not deem ourselves as being in the power to judge what property we can damage ourselves. Sounds like something I could live with.
