But similar to any other "product" the evaluation depends on the user's needs. As a single guy I loved that NYC was dense and walkable - because that meant (among other things) literally millions of date-able women within a 30 minute walk radius of my house. Great! Now as a dad of 3 I don't care about that at all - and the lower density suburb let's me have a backyard for my kids and makes shopping easy, or taking the kids to activities (yes you can do all those things without a car but people chose not to when they have choice)
There should be some sort of mom-friendliness factor in these conversations. If my whole town is old people, terminally single younger people and migrants (as seems to be the case for the city in question) then high density walk ability is perfect. What's the density and transportation situation in places people actually have kids?
