Somebody builds a maximally efficient, hellish dystopia of a simulated city with no roads, no cars, and everyone's needs provided for within one city block if not a single building. Hackernews gasps in awe, then goes right back to lamenting the existence of suburbs, calling for bans on personal automobiles, and wondering why their city doesn't have superdense "walkable communities".
This isn't the only possible (and not even a likely) outcome of walkability, lack of need of cars, and localization. It's just exploiting the quirks of the SC engine to max out population with a lot of commentary slapped on to it.
