People do a lot of inconsistent things, a pretty bad one among these is complaining that housing is expensive, and then paying ~40% of the cost just for land every time someone wants to live somewhere, and when folks recommend putting homes on top of each other a plurality opposes this. (insert surprised pikachu image)

Of course there's a lot of things to automate. As I mentioned in this comment half of hard costs is labor.
