Also the other obvious answer that people have been doing for centuries is multi-generational households.
It's not the end of the world to live with your parents (or your partner's).
I think we could see a lot of pressure towards that as Western total fertility rate continues to decrease and larger population groups (Millennials) age with fewer or no children to help out.
Even a shift towards non-relatives households wouldn't be the end of society, it would just be change (and require some zoning/code changes).

This is cultural though. In the US that certainly seems very true. In other places (such as where I'm from), living at home with parents until marriage is the normal default.
Cultural...and economic. I guess in places where there are arranged marriages, or living together is shunned upon, this is true. However as far as I can tell generation z is complaining about the economic situation that disables them from moving out. So it's definitely not cultural there.
