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.

First year economics doesn't ignore any of this. There's behavioral economics and microeconomics, for example.

Ah yes, that 150 year old meme reflexively copy-pasta'd by internet commenters since the days of usenet to refute basic concepts like supply and demand.

"Lol economists are dumb they think humans are robots!"

No they don't. Sorry, we won't be throwing away an entire field of human endeavor based on a straw man caricature that isn't true.

We don't call physicists dumb and throw out their ideas because the real world isn't a perfect vacuum either. They know this, don't be silly.
