> What matters is if Amazon clients actually do go around Amazon or not. I disagree. If every freely chooses to buy from Amazon when they could have bought elsewhere, that doesn't mean they have a monopoly. It means they offer a superior product (or a superior price). As soon as someone comes along and offers a better price or product, people will stop buying from Amazon. Power still lies with the consumer in this case; government regulation is not required.
