People want a lot of things, many of them conflicting. I'd love a huge house on a large lot in a walkable area and it to be cheap, and also close to nature. Letting markets work is a good way of resolving people's revealed preferences. Some will prefer a condo in a walkable area, others a large lot outside a less expensive city, others will pay through the nose to have a single detached unit in a high cost of living area.
