Try telling that to people who live in once-pleasant single family home neighborhoods where high density housing is replacing it. I don’t think that they will find your argument persuasive.
I say too bad, change happens, get use to it.
In 1906 Las Vegas was 6 stick built one room shacks, things changed since then
Neighborhoods change, populations change, demographics change, it going to happen, building more roads and building single family homes out in the middle of some woods or field is very expensive, building up and higher density living in high demand areas is cheaper and will allow more people to live closer to work and town/city centers.
Nothing stays the same forever, it either grows or dies..
