Respectfully, this argument reads like it is completely ignorant of the e-commerce landscape over the past 30 years and how much Amazon has shaped and innovated in the space. Not to mention that today they have several verticals beyond e-commerce that make up their valuation.
Okay go on and count only half for the sake of argument. That's still a trillion. Any business can do what Amazon does for their products and their customers. But they don't and they won't. Those who do experience great advantages.
