However it doesn't hold - as your neighbor I can't bar you from putting up a fence because it'll intrude on my view of your property... granted people try to do that _all the time_ but I think it's commonly understood that putting up a fence for privacy is allowed. It's also not a great analogy for this case because another party is given continued easy access to view my backyard while the first party is denied - and the analogy breaks down here because, as a neighbor, I have no inherent right to view your private life at least as much as any of your other neighbors.
