I was attempting to drive the point that we've gone from "you can be interrupted at any moment when you're home in and be expected to host friends" from "I get severe anxiety if I get a phone call". Clearly there's a point in between, or do most people really like the hermit lifestyle? Even if some people in here are genuinely busy with hobbies, side projects or genuinely lead a busy life, most people I know that express this point of view are most definitely not doing anything remotely interesting with their free time.
The fact that extreme social isolation (either on purpose or not) is one of many factors that can lead to steep decline in mental health suggests that behaving like this is not good for us, yet a life of "do not talk to me ever, email me if you must" is always seen as the perfect end goal in most of these discussions.
