I don't have a magic bullet solution to what a home renaissance could look like. In some ways it might require re-thinking what home is. Maybe taking inspiration from indigenous long houses with 10 families sharing a space would be a good step forward. It could be more sustainable in terms of energy requirements, solve for some of the loneliness issues that are prevalent nowadays, as just 2 top of mind things.

But our culture is very individualistic and values greed and puts exploitation of others on a pedestal. I don't believe this would really work with the predominant mindset of meritocracy or even be appealing to most as we feel entitled to our own space, ways of doing things, property etc.

We see community and the related obligations as a burden and put the individual at the top. I think changing this would be a preliminary requirement to solving homelessness.

Not that I have thought this through from all angles, but I believe this is a major blocker.
