You're still missing the most important component for affordability: more housing. Not simply conversion of existing market-sold housing to price controlled, but more.
Lets say that everything gets converted to rent-controlled in an area. A child becomes 18, graduates from high school, and wants to stay close to their family to maintain their emotional connections. If everything is rent-controlled, but not enough housing is built, they have to be on some sort of waitlist or lottery to stay in the area. This will push out so many people.
The only solution is to make enough housing for the people that want to live in an area. Without that, we are rationing it by price, by lottery, or by waitlist, and all of those will destroy the emotional connections that both you and I want to maintain.
