"naturally surounded by high rises" nothing natural about that. Its callled urban planning and in this case complete control was given to one guy, the one that made prospect park too, i saw a docu on it. Sometimes it works out, sometimes it doesn't but the bearucracy and corruption with funding usually takes its place. A lot of cities simply weren't planned for that, central park is designed pre-automobile. Many new cities are post-auto, so they dont care about walking spaces like they used to, a lot of cities have decided that the public is dangerous and hard to control, they dont want them to gather or loiter in any space and why should they give something for free when a business can profit from their need? NYC came from a place where they the populace was accustomed to dealing with the public in person on a daily basis.
