> In a village, everyone knows everyone. Kids play with each other and run around freely. Every house protects all the kids and help each other. Everyone trusts everyone. You never feel lonely. Life is slower, much less stressful.

That just means we need to structure cities differently.

I live in a 1 sq km neighbourhood (literally, 1 km square) that houses 10k people.

It has almost everything I could wish for at walkable distance, schools for all ages, parks, a gym, a pool, sports campgrounds, medics, pharmacies, stores, markets, etc.

What doesn't exist (e.g. a movie theater, a library) I can reach by public transit in half an hour. The city has 2M people, there's plenty of stuff to do.

I've lived here all my life, my kids go to school with the kids of my school mates. They walk to school from at least 10yo, they visit each other's houses. During school breaks and weekends, they play in the park with their school friends while their parents grab a beer in a nearby kiosk.

You can build communities like this within cities.
