Having grown up in a world where such things as brutalist architecture were imposed on all of us, I feel that when somebody gives me a say on the visual aesthetics of "my" town, I'll be more inclined to agree with the right of a neighbourhood to control the appearance of an individual's property, though I have some sympathy with the neighbours. It's hard to see a code of conduct that wouldn't involve somebody oppressing somebody else, so maybe anarchy is the nearest we can get to perfection here. Our city council doesn't allow small, tasteful windmills, on the grounds of aesthetics, but they don't stop satellite dishes of the same size. And they claim to be serious about green ethics.
Does the individual have a right to see only beauty as they go about their daily life? It would be great, but I don't see how it could be done. Everybody would have a different idea of what was ugly - mine would include most advertising and the Tesco logo, most cars, many modern buildings especially shopping malls, those yellow lines on the road, fluorescent colours, police uniforms, used beer cans, football flags, car parks, people in silly trousers, baseball hats, and business suits.
