I agree that the things listed in this article need fixing, but I also feel like they're missing the point.
I grew up in a small college town (in a house), but have spent most of my adult life living in cities (in appartments). Somehow, those cities have never felt like home to me. I've always felt like I was missing something. Privacy is not quite the right word. Perhaps solitude.
Growing up, I could easily find space to be alone (and I mean, truly alone) . In my current city, there is literally no way to do that. My appartment is cramped, and low sound isolation means I can hear the neighbors. If I go outside to the park, there is approximately a person per couple thousand square meters (and the noise carries further). If I go to a coffee shop or other public place, it's even more crowded. I can go to the mountains, but it's about an hour by car to get there, and even then there are people around. (Unsurprisingly, the further I have to go, the less likely I am to do it on a regular basis.) This inability to have space has lead to a sort of mild chronic anxiety. Suffice it to say, I don't like cities, but I'm stuck where I am for other reasons.
So I can't exactly say I'm eager for even more population density. Some of the problems above could possibly be mitigated (e.g. better sound isolation), but the broader issues of how much personal space is really necessary just seems like it's not on people's radars. Is this just not an issue for other people? Am I crazy?
I hope that any discussion of better cities includes this as a component.
