Very interesting, the theory that certain objects(eg art) cannot be privately owned, but must in some sense be communal property. Land, and stately homes and other buildings of a certain status tend to be considered in this light as well. It makes senses, though I'm not sure if I fancy everyone having the right to stroll round my house looking at my attempts at Zen calligraphy. An intriguing moral conundrum.
    I am not sure that I want a part share in Damien Hirst's shark, but I wouldn't mind a 60 millionth share in Stonehenge or "Flatford Mill".
