Example: You can't shut off somebody's electricity or water because they are a bad person, or have expressed unorthodox opinions. But you can shut off their twitter, their email, their web search, their facebook, their linked-in, stop processing payments for them (potentially cutting them off from their livelihood). You can cut them off from their digital identity and shut them out of the digital "public" in a manner of speaking. When that happens right now today, people hand-wave it away because "X is a private company they can do what they want." Never minding the fact that X has become how almost everybody addresses/interacts with the rest of the public digitally, or how X has ALL their email data, and many important documents etc Getting locked out of these things is not life threatening in the way that no water is, but it can essentially delete somebody from the "public" with almost no recourse.
