I was briefly interested in tossing in my lot for Chateau Blavou, simply because it is gorgeous and I think that with 10 bedrooms, a caretaker's house, and a guest house the estate could probably support 7 families at least. I engaged in a 21 Balloons fantasy where the Mustachian families living there took turns cooking for a week at a time. Hey, we'd be Mustachians, and we'd have the time. We'd have enough community to have cool people to hang out with and few enough people that we could closet ourselves away.
But I can see that a mini ERE city in the form of a French estate isn't to be. It's a bit funny, but I've got quite a bit of family in France. Comtesse de Vogue (probably not spelling that right) was my aunt's godmother and her husband's family had a business renovating their chateaux and renting rooms in them out like hotel rooms. I think that those are in the Loire Valley, but I'm not sure.
I'm seeing that this thread transitioned over to talking about islands and someone wondered why companies didn't just plunk down somewhere tropical. I can haz cheezburger (referred to employees as "cheezburger") actually ran the numbers on setting up shop on their own private island. I had this conversation with one of their software engineers. Over the short term, it was cheaper/neck and neck with their cost of operating in NYC. Over the long term, though, it was expensive to put in infrastructure like hospitals and schools. The nearest hospital to their proposed island was just too far away, even for medevac helicopters. So they remain in NYC.
