I agree with David's general thesis and the items on the list except for the App Stores.

Naturally government-oriented influences like the patent system and regulations are monopolistic. Net neutrality is monopolistic because the backbone infrastructure is in the hands of a relative few number of infrastructure owners. Often, where you live determines the connection to your house and that's a monopoly often enforced by municipal contracts.

App Stores are the only item on his list that are not quite monopolistic in nature. As such, new competitors can come along at any time to unseat App Stores that are failing to provide enough value to consumers.
