The end point of the argument is that there is no such thing as individual privacy. Privacy is defined by the ability to distinguish people, even if it’s just process of elimination (you know that all but one of the houses on the block has a smart oven, and you can figure out that somebody in the block turned an oven on based on the minute changes in natural gas pressure, therefore you can spy on that last person almost as effectively as if they had installed a smart oven themselves).

Either everybody is private, or nobody is. There is no such thing as “f u, got mine” here. Privacy is inherently a collective problem, so it must be solved by political means, not by individual choices.
