What will this solve? What if a fire breaks out? Can protestors block a single street? Where are people going to dry clothes? Won't those who live at the base feel claustrophobic?
As to social aspects... That is my major concern also. Of course this city has a police force and would clean up anybody blocking the central hubs. There is no street btw, but rather different kinds of corridors for walking and trains of different speeds and ranges. I guess it is relatively easy to disturb the system, on the other hand if realized there would probably be an authoritarian kid of police force making sure nobody does.
People are moving out of dry cleaning into "wet cleaning" to avoid chemical solvents. Wet cleaning requires a drying machine.
