The problem is that Amazon is now basically the market itself while at the same time a competitor or a potential competitor. Small businesses don't have much choice in the matter if they want the ability to reach an entire market. If they go their own way and build their own retail experience, there is a ceiling on the percentage of the market they can sell to. Without any regulation to curtail this behavior, the end state seems like it will have to be Amazon owning the markets that have the best margins and the least risk. Competitors will die and Amazon will be able to increase prices to maximize their profits without needing to worry about being undercut. That sounds exactly like what anti monopoly legislation was written to protect against.
