Why not just move to a dense city or downtown? How can a random developer-planned concrete mixed use fortress possibly achieve the nature of a city? A street in a city is a market. People compete to offer the best goods/services/experiences based on the what the local people want and this organically grows into something interesting. If one person plans it all out from the get-go it kind of loses the sheen of any level of culture/unpredictability that makes living in this setting appealing. This feels like a repackaging of those McMansion neighborhoods in a cute urban millenial flavor.
