Sure, we have anecdotes about how not every property is a profit bonanza, and that there are often a bunch of surprise costs. That's why there are big development companies. The advantages of scale apply here as much as anywhere. Lose money on one, make money on others to offset the risk. What you call a "simplistic fantasy" is a century-long phenomenon in the US at this point of increased population in major urban areas leading to rising land values and the conversion of empty fields into developed areas. There's no guarantee that population growth will continue to increase demand, or even that demand in developed areas will stay high - there have been a lot of cycles in that time as well, with extreme examples like Detroit to balance out the SFs of the world - but that's a very different argument than "we need to increase development so that we make housing less of a good investment," which I'm claiming is a blatant contradiction when it comes to the value of the land that is being developed. A shitty house in NYC is worth more than a nice house in Austin not for the building, but for the value of the slice of land it sits on, because the area has been developed more which has resulted in more demand.
