Bookstores are different from "physical stores" in general because books themselves are arguably obsolete.
My $50 Fire tablet can hold 1000+ books in PDF form not to mention Kindle format, HTML, etc. It's almost as good as "read a penguin paperback" on the bus or in bed.
Go to an academic library and you see the stacks are empty (of people), books rarely circulated, but people are crowded around the computer terminals. (e.g. smart introverts go use the terminal deepest in the stacks)
"Books" as a form of literature could survive the end of physical books quite well, just as "Movies" could survive if the theaters never re-opened and it was all direct to video.
Contrast that to Lowe's or Kohl's or some other store that sells physical objects that are still in demand.
B and N tried the "build a community space with free WiFi" but in our town it became a downmarket version of the public library (another five minutes from the police station) and one day they "kicked the bums out" and as I walked by an Asperger's female with poor hygiene was complaining about it.
