I don't think this article makes a logical argument at all. It says house ownership is bad because it gives people a vested interest in constraining the supply of housing. That's true but that's not a problem. If people didn't own houses then someone would, and that someone is still incentivized to constrain the supply. I'm also not sure that reducing home ownership is a good idea - "let's make everyone poorer" doesn…
What this fails to acknowledge is that the demand for density doesn't change when you outlaw it. All you've done is taken away people's choices, mandated your own preferences, and still in the end all the same demand for more housing goes on existing just the same, anyway, so prices continue to rise.
It may be true that all things being equal most people prefer detached single-family housing, but all things aren't equal! And so we have to acknowledge the tradeoffs and take the demand for more density seriously. (The fact that in order to get detached single-family housing in high-demand areas you have to make the alternatives illegal is I think pretty strong evidence for this.)
