I don't see why it's an issue that he owns two rental properties. Of course he has investments of one kind or another, that's his shtick. Save money, but income-yielding investments, retire. Whether you buy properties or live off the dividends of your XOM shares (or more sensibly, do both) is immaterial. If your point is that it doesn't scale because its literally impossible for everyone to have two investment properties -- well, yeah. Frugality doesn't scale well. If everyone else stopped buying shit they don't need and working more than they needed to, production would go down and yields of all investments would suffer. So it's not actually a good idea to persuade everyone to quit buying shit they don't need, but it's advantageous for every individual to do so.
