> Assuming a family of 4 would live there instead, she's effectively removing 3 people from the city.

I think is overrated concern in general. Most popular cities aren't underdeveloped. Rather the problem is concentration of resource. Having less optimized areas are actually a good things as that means more areas are equivalent. Which is really what supply is in housing markets. It's when every one too young, old or poor have to move you get problems because now all the attractive things are in the same area. Which means the demand will be very high.

Also this is happening in the housing market in general but apparently it isn't a problem when it's wealthy people retiring in their forties because of the housing market itself.

> There's a gradient of prices as you move further from the city center, and this particular hypothetical woman is moving to a much smaller unit.

That is mostly true if you are moving voluntarily. Because if you couldn't find something beneficial you wouldn't move in the first place. It isn't as true when you are being forced to move. Often it isn't even about what you are moving to but what you are moving from. Once you can't live close to your family, acquaintances or familiar establishment it doesn't matter as much.

It's sort of curious how so many seem to agree that we are "losing our values" in society (or whatever) but then base everything on assets. If we want people to be able to live close to their grandchildren, know their friends from growing up, involve themselves in organization or otherwise make social connections it isn't going to be free.
