No, because while you own your house, the billionaire owns every house on the block. What happens when all of those houses get liquidated at once?

More importantly, and the part of the quote you left out, is that in this analogy, the houses can no longer be rented and a revenue stream dries up.
So no, it’s nothing at all like your home equity.
