It just makes sense that when many people want to live in a small area, that you allow builders to meet that demand. Having sex with robots? What are you even talking about? Plenty of people would rather sacrifice the large spaces of a single family home so that they can be close to an urban core. It could be because they want to be closer to their work or just want to enjoy the environment of the city. It's just as much a quality of life issue when they are priced out of that.
