I have no clue why you would think this. Basically ever poor person I know (and I know a lot of poor people) has simply given up on ever experiencing home ownership. None of them can afford to live by themselves. High density or low density, zoning laws, etc, don't even enter the picture because not one of those will actually bring housing into any kind of affordable range. It's just that politicians refuse to campaign on anything but "what type of housing supply should we hope developers build—low or high density" that there's any confusion here.
