Amazon and Walmart can at least be challenged or fail no matter how unrealistic that is, government owned monopolies are there to stay and can't be challenged. You can choose to shop in places other than Walmart and Amazon. It's really a question of a centralised government monopoly or a decentralised market that has the potential of creating monopolies/duopolies. Yes the market can be dominated by a few multinational corporations but it's still not a complete monopoly, you can create alternatives, you still have choices. To create a monopoly in this space requires a huge continued effort whereas under a state owned economy it's a monopoly by default.

It's not even that unrealistic. Sears was once the largest retailer in the world.
