>That among humans rich with agency, there's inevitably someone who can see the opportunity in restricting access to the unlimited supply of ice cream as a way to control others and reduce their agency.

I think that is a real phenomenon, but different. The article seemed to focus on new technologies that are being brought into existence. It is one thing invent ice cream. It is another to figure out a mechanism to monopolize ice cream access.

If someone invents a new flavor of ice cream and monopolizes it, are they reducing the options available to individuals? What about if it is so good that nobody wants other flavors? What if the other flavors stop being made?
