Amazon started as a bookstore.
That is worth sitting with for a second. The company that reshaped global retail began by selling the exact product that independent bookshops sold, and it destroyed most of them doing it.
Borders is gone. Thousands of independents closed. Barnes and Noble shrank dramatically and changed hands.
Meanwhile, in Portland, there is a bookstore occupying an entire city block.
It has been there through all of it, and it is still there now.
The usual explanation is local loyalty and civic affection, which is real but is not a business model.
The actual reason is a shelving decision made decades ago that turns out to be structurally impossible for an online competitor to match.
