I think what’s lost in your response is a recognition of San Francisco operating as a metaphorical symbol of certain principles (as embodied by the icons our dear author referenced). To reference the inception of San Francisco, when an identity hasn’t truly formed, is out of touch. Before the “legacy” of industrialism you seem to associate with my dear city, this was the Barbary Coast, a town for sailors. A town for pleasures, dreams, characters, adventurers, and bohemians. Do not attempt to label SF as a poster for capitalism, it has most always been the classic collective of hedonistic freed people. 
In our countries short existence, SF has cultivated stature as a place For the People. A civil rights monument, grass-roots garden, working class utopia for the laissez faire outlook. Let people live, and I will live my own way, and we will live, Together. 
So ironically, what I will care to respect about this influx of uncultured, generally biased, and agonizingly socially awkward folk, is their call to embody the hedonism of our history. Because perhaps, this will create a bit more of an equal outlook because as they say, we all fam in da club.
