This is wrong. The network effect of sellers and prime customers is more powerful. For most if not all of our products we could have cheap 2-day prime by negotiating with carriers if we had the sales volume.https://twitter.com/modestproposal1/status/1146404882313895937 …

Also, in a minor way, trust. My ebooks can be bought on Gumroad. Yet, many readers purchase them on Amazon because they trust Amazon but not Gumroad (even those who don't own Kindle; some message me specifically asking if I sell on Amazon bc they don't trust that unknown website)
Amazon is a lollapalooza of competitive advantages: 1. trust 2. network effects 3. scale 4. technology 5. vertical integration 6. stickiness (prime) 7. brand I could keep going
