You being unhappy in your life does not mean that there is anything wrong with the world. Looking to pin the blame on society at large and other people's choices is a convenient escape from looking at yourself and your own fears, disappointments, choices made, etc.
I grew up in a rural place, no mountains but we substituted beaches, marshes, and ocean. When I go back to visit I can't believe how beautiful it is. But, I prefer to live in the city where I can walk to coffee, pizza, chinese, mexican, etc. I never visit city parks, the grass and trees don't speak to me at all of nature and as an engineer I see beauty in architecture and construction and (after studying economics) the dynamism of human striving.
It's fine to decide to drop out of the hurly-burly, but don't call your fellow city dwellers rats, they're people making a go of it. The carbon footprint of the average New Yorker is among the smallest in the world, that's what population density gets you, and rural areas? they're filled with human suffering, don't kid yourself.
