I'm really struggling to interpret that charitably but I'll try -
Some reasons to live in a big city: (1) It's where your friends and (perhaps elderly) parents live. (2) It's where your job is. (3) You can't afford, (or don't want to own) a car. (4) You're single (especially true if you are LGBTQ). (5) You like the cultural opportunities it affords. (6) You have access to specialized medical treatment. (7) You run a business. (8) You're getting an education. (9) You're too poor to move. (10) You don't like narrow minded, holier-than-though attitudes that tend to be more common (IMHO) in smaller towns.
Have you ever been to San Francisco?
For me it is the small places that are the perpetual cocktail party/high school where I "have" to get along with everyone instead of picking my preferences.
This is ironic, but I hear it a lot from people living in big cities. I live in a sparsely packed city, but mostly know who lives in my neighborhood. We were unhappy with the last city government, so we replaced them, and it took a lot less people to do so, in absolute terms (which matters because the relative size of your movement only comes into play if you can manage to have a movement at all, and that depends on the absolute size of the movement (1000 people are easier to convince and coordinate than 10K)). My metropolis-dwelling friends keep sharing how lonely they are all the time.
I never got the logic behind living in the perpetual cocktail party/high school that is a big city.
