> The more remote your living is, the more everyone else is subsidizing your existence.
This is an uncritical viewpoint, you're simply describing a society. It doesn't matter where you live, you're soaking up the labor and capital of the wider net of people. That's what it is to have a civilization, and ours is so deeply interconnected that all relationships are inherently reciprocal. The trivially measurable flow of money doesn't say anything of substance as it's a second order abstraction, only that the mechanisms and pipelines by which money move are situated in cities. It's not urban labor and urban resources that builds, maintains and operates that infrastructure or the social fabric that it serves and is served by.
> It's one thing for the people who already live there or genuinely need to live out there, it's another thing for people to choose to live out there for "personal reasons".
On the contrary, the negative health effects of cities are empirically measurable[1][2][3]. We should be striving at all times as human beings to move past having them at all, and should look to building towards healthier, lower density living and encourage it for anyone who is capable of doing so. We cannot fall into the trap of building, encouraging and valuing objectively worse living conditions in the name of efficiency, the entire point of this whole system is to lead better lives, not to make the numbers go up.
