I'll admit, it is an interesting thought experiment to explore what a society would look like with a 100% moratorium on rentals. It seems like you would have to do away with down payments or there would be widespread homelessness. I imagine mortgage rates would be through the roof, as new occupants wouldn't have equity in the house to protect.

Owner occupation rates are about the same since the 1960s, and worse before. I wonder if there are examples that approach this ideal. Perhaps family homesteads during the US westward expansion, but even then there was a lot of landless workers.
