While this is true, I think the bar should be lower - the real question should be "and how does it compare to renting" - there is very possibly a universe where owning is cheaper than renting even if your home depreciates. Because paying some amount for years to be left with a fraction of what you put in is better than getting none of what you put in.

However many of us knowingly exceed that point. For example we pay ~$500/mo over that point. Though there is no really comparable rental, we definitely could have chosen a more cookie cutter rental to be about +$6000 / year.

We would expect them to be equal on the margin if the market is even somewhat efficient (not always true with rent control, but still pretty close in most places).

That doesn’t mean it’s equal for any given individual of course. So it’s important to do your own calculations and make your own decisions. But I think the fact that it is debated so much shows that it is probably roughly equal on the margin.
