Unfortunately, mathematics and economics severely limit the
scalability of this approach. There's only so much space within
walking distance of each station. Once that's filled up, everyone
else has to live and work elsewhere. And if that's the most desirable
space, it'll quickly become enormously expensive because it's both
desirable AND rare, meaning only the wealthiest people and companies
will locate there.
