NYC is highly walkable, and very large. Same with London.
The benefits of large walkable cities is that people get motivated to do urban 'hikes' and the hours of exercise are much larger than in typical cities (especially compared to walking and cycling unfriendly cities).
As far as 'conspiracy theorists' this represents a vast spectrum of individuals, and no doubt that would be foolish to lump into a single one-dimensional stereotype unless your aim is some sort of propaganda or social conditioning.
