If your thesis was correct, it would be evident to the author who is actually time-sharing (taking advantage of all the things you say). But what he describes in his essay is how even he is of a different mindset...this essay is more about context switching. Its impossible to context switch when you never leave the house/office/facy neighborhood. Or to use some data, look at the dismal % of african americans that go to yosemite or even know how to swim. There's lots of racial and historical bias at play in that data, but the empirical point remains--context switching for urbanites is hard. And the poorer you are the harder it is. The reverse is also true--the poorer and more white you are in appalachia, the less likely you are to context switch with the weathy coastal cities. So we have money and culture paying a part as barriers to context switching, notwithstanding the revolutions in transportation (train, plan, auto, jet) and communications (telegraphy, telephone, tv, internet...etc).
