Why convince them? If they never go outside, they’ll just be inside anyway. You won’t interact with them. Metaphorically. Real life is a place, not an idea.
You're interacting with real people who doesn't see your face and hear your voice all day and affect each other.
Real life is a place encompassing the "cyberspace", too. They're not separate but intertwined. You argue that people affecting your life are the closest ones to you, but continuously interact with the ones who are farthest from you distance-wise and they affect your day at the moment.
People who want billions of people to be inside and compliant, want those people's vote to go a certain way (at least, while that is even still a thing). Once that part stops being a thing, you stop being allowed to be outside, as that could be a problem.
Not invalidating your viewpoint and I'd bet we are pretty well aligned, I too have a pretty local-first view and that as a country we put too much emphasis, energy, and discussion on national politics and could all benefit from "getting outside". That said, I did want to point out that this comes across as a very self-centric viewpoint, one that would differ greatly depending on who you ask. Even as an anecdotal story, it offers very little to say about the current state of affairs related to how people voted, which would appear to be the intent of the response.
As a bit of a semi-related aside, while everyone has different motivations when voting, as a whole when folks are able to vote for their gov't, one hopes that enough people are thinking about what is good for the majority and society as a whole and not only what is good for themselves. And that has more impact at local and state levels usually. A bit idealistic, admittedly.
