Currently we make it illegal for the current owner-resident to choose to bulldoze their single family house and build a quadplex and live in one unit. If you don't want to redevelop your lot that's perfectly fine, but why restrict your neighbor's property rights? The current system just rewards those lucky enough to see their neighborhood appreciate in value. Once it does newcomers are priced out and we have an equilibrium of urban sprawl, housing inflation outstripping inflation, and ever longer commutes. Imagine if groceries were sold on a 30 year contract. If you chose the right grocery district you'd eventually get a sweeter and sweeter deal as your right appreciated. In the most competitive grocery districts, newcomers would have to bid $1 million to for the right to access groceries in that area. Or rent it at $3000/mo. Faced with a too high cost to buy into a centrally located grocery district, many would have to commute an hour each way to stock their pantry.
