But if you put a billion houses on Manhattan their value will be zero. There's almost an unlimited amount you can build up. The problem is we're currently putting houses on Jupiter instead of Manhattan through arbitrary restrictions on density. There's single-family zoning in San Francisco! 94% of San Jose. 15% of NYC (25% if you include single and two-family zoning). It's wild.
