May not be a popular opinion but I'd have to say that I value the idea of having space between me and my neighbors, so I'm definitely not in favor of maxing out the land for homes to the point where the houses might as well be attached and labeled condos or apartments.
I can understand where the people are coming from in wanting to maintain what they've invested into. I'd hate to see a sudden boom in population and sudden traffic spikes due to the knee jerk reaction of building 100's of more houses in an area that wasn't even planned to support more than what is existing.
People do need housing but people also need to be realistic about where they live and how they plan to keep on living there.
