If everyone lived in 20 story apartment buildings there's be massive amounts of space no longer used for low density housing that could be freed up for parks etc.

My road alone takes up around 40,000m^2 to house and transport about the same as housed in 2,2000m^2 near the local train station.

To late to edit now, but in case it was unclear that "2,2000m^2" was meant to be "2,000m^2"
