All else equal, I can see why the ability to live in the same house until you die would be given a high moral value. But in practice, IMO, this culture causes a number of problems. For instance, where I live, there was a lot of growth in the 70s and 80s, and a lot of young families, so they built a bunch of schools. It's an attractive place to live, so a lot of those people who lived in those houses when they were new and raised those families and attended those schools have kept living in those houses. But those kids that they raised there can't live in those same neighborhoods as adults, because there's no turnover, so they can't raise their own kids there. So now the schools are all half (or less) full, because the neighborhoods they were built to serve no longer have a lot of families living in them. So then they have to close and consolidate schools and everybody hates that. I don't really have a strong view on the moral question of whether houses "should" be owned by older people who have lived there a long time or by young people families, but from a pragmatic standpoint, this situation seems quite bad to me.

I think if we had a totally different culture, with multigenerational families living in the same house, then this might work better. But this model where we build new family friendly neighborhoods with parks and schools, and then nearly everyone ages in place and all the family amenities become empty over time, and the families all end up in the next new neighborhood and then it repeats, this doesn't seem ideal to me.
