I can't be sure, but I expect your definition of "anti-competitive" is so broad that it becomes inoperable in a practical sense.
My local bookstores do not offer electronic delivery of books. You figure that, until they do, Amazon can't offer them to me on whatever device I want to read them on? I, as a reader, can't use new technology because a local business only sells dead trees?
That's like saying that Spotify has to die, because it undercuts BASF's audio-cassette business. Or Ford can't sell cars built on an assembly line, because it'll put buggy-whip manufacturers out of business.
So, I can totally understand having a beef with Amazon over a lot of things. But, just because some of what they do is problematic, does not mean everything they do is anti-competitive. The advance of technology makes new types of products available. If you make it "anti-competitive" for others to enter those businesses, we don't get new products.
