"Are you proposing that everyone in SF move to places like the Central Valley (driving up price) and start driving around cars (increasing traffic and pollution)?"

I don't know where you came up with this. The OP implied that by moving away from a heavily populated area and working remotely, he was able to afford more space and shorten his commute. You managed to turn no commute into increased pollution and moving to a less densely populated place as "driving up price"?
