Building a city/neighborhood is a really bad example for an agile development tool: agile development is to be used in case requirements are not yet fully available. In other words, the team is searching for the right and best solution to solve a problem. In the author's example, the city is already fully planned and ready to be build, thus the solution to solve an existing problem already exists. Why to use agile? Building a city/neighborhood is a perfect example for a waterfall implementation strategy which can be perfectly modeled with other tools. As always - use the right tool for the right job and you'll be alright ;)
