> suboptimal but creative solution I saw recently was neighbors working together to remove their backyard fences to create a large and safe play area for children in the suburbs.

This is something I would love to do, but still feels so impossible. I see some homes compromise and put gates in the fence. Where I am, I see probably 70%+ of homes with backyards using them as bathrooms for their dogs, and I imagine that many people would have a problem just with the basic social contract of who cleans dog poop.

Particularly due to COVID, I've begun to appreciate just how severely the suburban structure negatively impacts all aspects of our lives. You have HOAs that invest in common playgrounds, cities that have invested in parks, and virtually everyone reports extremely high satisfaction with these things. Yet my own feelings of isolation tells me that we need much much more. I'm at the point that I would seriously seek out and move to a place with a walk-able kid-friendly setup. But it just doesn't exist.
