Somebody painting your personal property (which invokes the image of a home or point of sale shop) is a miniscule subset of all cases of anybody "seeing graffiti". Also, the author doesn't call into question your rights. I see this a lot: Being asked to do or even just consider something, and falling all the way back on rights as an angry retort, which is irrelevant to the request. He didn't say, "do this or I'll sue you."
