> You may not want to live like that, but plenty of people do. We should allow them.
I suspect that number is a lot lower than is claimed. It's only a very loud set of vocal urbanist activitsts who clamor for these changes and create the illusion of that demand. The reality is most people grow out of wanting to live in dense areas and walkability is very overrated. In fact walk scores basically don't matter when people actually shop for a house compared to other factors (price, size, location, schools, etc). And as people age and want to establish a family, the urban life quickly loses its attractiveness.
The real question is why should any neighborhood have to 'allow' anyone who wants to live there to do so? Am I entitled to living beachfront in Maui just because I want to? Should they have to change their zoning to permit that? I feel like incumbent residents have a right to maintain their neighborhood character, density, and quality of life. Those things get eroded when you have an influx of new residents and different density - you end up with streets, parks, and other amenities that no longer work the way they're supposed to. What I see happening is that a city will build itself over time into something very attractive, and newcomers want a piece of that, so they demand zoning changes at the cost of the incumbents who made that place attractive in the first place.
