I'm not saying we should bulldoze all the single family homes and make everyone live in filing cabinets. What I'm saying is people should be free to choose. We want the people who enjoy living in cities to have a place to live IN the city. This makes it so they don't have to spread out across the country side ruining farms, natural areas, and stuff that is better out in the country.
In fact, this would make it easier for you to afford a single family home and make your experience much more pleasant. You wouldn't have 10 neighbors complaining about the sounds and smells of your animals or report you to code enforcement for your plants growing too tall. You also wouldn't have thousands of cars going by with broken exhausts as people commute to work.
In addition, you could live much closer to cities to go see sporting events and concerts because the availability of single family housing would be much better. Also, your race tracks, animal rescues, nature parks, hunting areas, and other rural features wouldn't be regulated to death by massive suburban developments taking over.
