I mean, when you’re not being hyperbolic it’s absolutely possible. You can easily have a walkable/transit oriented city with lots of green space

Edit: it also doesn’t even need to be that dense. Like most of my city’s downtown is a lot of old houses rather than endless big apartment towers. The difference between my neighbourhood and American style suburbs is that I have multiple nice high streets within a ten minute walk and can get by without a car, while still living in a three bedroom house
