Amazon is making more money than the entire economy of most countries. Their long term plan, like other tech giants, will be to become a sovereign entity. In some ways, they already are. Then they can effectively outlaw the competition, so outcompeting them won't matter anymore.
You can't become a sovereign entity without territory on which you can enforce your norms. Amazon doesn't and (for the foreseeable future) won't have sovereign territory.
You don't need territory, the Sovereign Order of Malta doesn't have any either. If you are in a locale where you can use the legal system to forestall any action against you, it's pretty much the same thing.
