Housing is also really weird:

- the main input (land) is also an output, so when the price of the output goes up, so does the value of the input.

- economies of scale don't really work, due to the impracticality of transporting the good (houses) and fitting the good inside a machine (in house "factories", normal workers go inside the house and work on it by hand; not a lot changes compared to traditional construction)

- more supply in one area increases the value (and therefore demand) in that area, so it's not actually clear-cut whether building more would reduce the price more than it increases it, at first glance.
