Well written reply so I'll try to address thoroughly.
>You're building an argument atop the assumption that if Amazon didn't exist, nothing else would be available.
I cannot be making this argument because Amazon exists and we have many other options. We also had many other options before Amazon. Despite this, Amazon became an e-commerce powerhouse. Why? I suspect it's because Amazon is by the far the best option for consumers and others are only close because they adopted many of the same guiding principles like fast free shipping and easy returns.
>Amazon's strategy is to spend money that no other company can spend (by forgoing profits) to be the fastest / cheapest option available. Bezos' innovation is not the "fast shipping" or "broad range of products" Amazon offers, his innovation was the foresight to understand how to dominate the market and the gumption to do it.
He dominated the market because he offered those things. How else would Amazon be able to overtake its much larger competitors? Amazon is not operating at a loss with external funding like many startups, it simply reinvests in itself because it makes incredibly impressive use of its resources. Other companies could do the same but as it turns out, it's quite difficult to repeatedly leverage your profits into bigger and better outcomes. Apple and Google sit on a pile of cash because they don't know how to best make use of it despite a history of successes.
>A single business that owns the sales and distribution of goods is one possible solution to the problem you describe, absolutely, and it's pretty clear that Amazon is doing the best job at that solution... but it's not the only solution, it's one of many.
Nothing stops me from shopping elsewhere and I frequently do. Best Buy gets much of my business for certain products because they've been quite good ever since their early 2010s turn around. eBay gets all of my business for used products. Walmart, Target, and regional grocery stores (not Whole Foods) get the rest. And I shop online mercilessly and don't have a particularly strong taste for Amazon (despite my countless comments in this thread would suggest -- I'm simply arguing for principles) so I'm as decent of a gauge for the state of things as anyone.
