What we lost when we stopped letting kids leave the front yard

I live in a low density, large neighborhood where kids 8-17 are out roaming all the time, the older half heading to adjacent shops and other neighborhoods. I recognize and know who most are and their parents. The common trend I see is a purposeful limiting of screen time.

That's not even the issue. Suppose that more people wanted to live in a city than currently do. The market implies that -- the price per square foot is higher in cities.

And that's the problem, when the city isn't allowed to grow. The existing city already has tall buildings, so if there is more demand than supply, to create more of it you need to add more somewhere else, i.e. build some taller buildings where there are currently suburbs. Which is the thing that's banned.

But then more people can't move into the city, even if they want to, because the units in urban environments are already occupied and converting more land to urban developments is restricted by law. So the existing units get bid up until the price difference is high enough to deter people from living in the city and everyone else has to live in suburbs or rural areas whether they want to or not.

It's a garbage world containing many garbage people and I think the "good old days" where you could just send your kid out in the morning and only see them at dinner never existed in the first place. It's just that predators can only prey on so many at once...

They're probably a lot safer in big numbers though, like if you had a group of 4 kids, each with cameras ready to film a potential attacker you could maybe give them ways in which they can protect themselves without necessarily needing adult supervision.

It's gonna be a hard problem to solve when I'll be a dad.

It's been spoken about a lot of times with philosophies such as 15-minute cities and there has been progress in Europe with promoting active travel and banning some cars from city centres. However, there's a lot of entrenched money and power that push for ever increasing numbers of cars and that's why the discussion ends up polarised.

Personally, I like Cory Doctorow's phrasing of "geometry hates cars". When places are designed for cars, more room is required for attempting to ease congestion (induced demand makes this futile) and parking, but facilities can be moved further apart as people are using cars to get there. That leads to more cars being used, which leads to more congestion, which leads to more space being allocated, which leads to facilities being spaced further apart. Rinse and repeat until cars are the only mode of transport which can be used.
