I was trying to draw attention to the fact that "I'm in the top 2% of earners but I can't afford a house" isn't surprising when legislative factors make it hard to add housing stock, when turnover is low, and when there's net population inflow.

My supposition was intentionally exaggerated to clarify what happens when you don't build enough housing: not to be pedantic, but understanding what happens in "extreme cases" is a common technique in math and physics to understand what happens in more common ones.
