This is a total strawman, and it just looks childish on badrunner's part (however consistent with his other strawmans). Even if that street doesn't look the most pleasant (I think it generally looks decent) it is without a doubt more pedestrian friendly than anything on the West Coast, so you've already lost the argument and make yourself look like a fool. Your attempt to belittle "cobblestone streets" with a bad example as evidence isn't fooling anybody.

Oh! Would you look at that! Narrow streets, wall to wall buildings up to the sidewalk, no garages, no curb cuts. Checks all the boxes for good urban form in America's most important city not to mention one of the powerhouses of the world. It can be done!
Let's take a look at one of the best urban neighborhoods in Philly:

From the perspective of somebody who appreciates traditional urbanism, this looks a thousand times more pleasant than anything California has to offer. I would definitely choose this location.
I also find it ironic that Philly's neighborhoods are being portrayed as depressed and uncomfortable when San Francisco is filled with vagrants at every turn, homeless camps, and stabbing/shootings in the city center. The idea that the urbanism in SF is more "comfortable" than Philly is laughable.
