North America does not have the same populations/density that is seen in east/southeast/south Asia. Therefore, North American cities do not have to make any such trade-off between density and green space.

In fact, density allows for more green space. Don't let single-family home suburbs fool you. Lawns are not green space. Laws are a pathetic attempt at greenwashing suburbs that were made by clear cutting forests or destroying nature. The less space humans take, the more can be left for nature.
