The problem with this angle is that people in general have to have housing, and so they're going to pay a substantial part of their income either on rent on on a mortgage. There's rarely an option to invest "the same money" in anything else.
Overall this seems like a solid analysis, but the contrast with "what else you could do with the money" seems a little weird when that's not really a choice (unless you live somewhere with a huge difference between the cost of renting vs owning).
