YC wants to BUILD a CITY – crazy?find out why (cities.ycr.org)

That link provides no information about why at all.

I just want to know who is going to pay for the wall we will have to build around it?

Not much info at the link, but if you go to the base domain, there's more info:

> Our goal is to design the best possible city given the constraints of existing laws.

> There are many high-level questions we want to think through, for example:

    * What should a city optimize for?
    * How should we measure the effectiveness of a city (what are its KPIs)?
    * What values should (or should not) be embedded in a city's culture?
    * How can cities help more of their residents be happy and reach their potential?
    * How can we encourage a diverse range of people to live and work in the city?
    * How should citizens guide and participate in government?
    * How can we make sure a city is constantly evolving and always open to change?

> And there are tactical questions we want to dig into, for example:

    * How can we make and keep housing affordable? This is critical to us; the cost of housing affects everything else in a city.
    * How can we lay out the public and private spaces (and roads) to make a great place to live? Can we figure out better zoning laws?
    * What is the right role for vehicles in a city?  Should we have human-driven cars at all?
    * How can we have affordable high-speed transit to and from other cities?
    * How can we make rules and regulations that are comprehensive while also being easily understandable? Can we fit all rules for the city in 100 pages of text?
    * What effects will the new city have on the surrounding community?
