> But if you can walk anywhere, what is the point of the megacities that seem to be fetishized in this discussion? I don't fetishize mega cities but I accept the fact that some cities will become the center of certain industries and thus naturally evolve into megacities. This is especially true of places like San Francisco (the city itself) where geography simply gets in the way. If a city finds itself in this position, there is no option but to build up. It cannot pretend to be a suburb. I don't even mean sky scrapers, but it would be nice to have like a four story building or two out of the main downtown areas, rather than the two story max that it seems to have now.
