Yes, I guess it does address the lack of exposure to the outside ; my point is that it must be quite difficult to disconnect from "the city" -- advertising billboards, noise... In this case, the outside is even completely devoid of life.

This concern doesn't stop me from being fascinated by urban megastructures such as the "LINE", I'm just not sure I would like to live in them (and I love living in a crowded city nonetheless!).
