If everyone wants to live in low rise buildings, why does the government ban building higher density buildings using zoning? If it’s so undesirable, nobody would move in so developers would have no incentive to build. It’s not wrong to want your neighborhood to never change. However I would argue that it is wrong to assume that every city currently has the “proper” density. Why was it ok for your house to be built but not for your neighbor to, say, redevelop their SFH into 3 town homes?
