Again I’m not saying supply isn’t an issue, and zoning is def a major problem in many states. But if the issue was only supply, rent would be growing more or less in line with the population not at the astronomical rate that it is.

When Vanguard and Blackrock own half of the supply, then it's not a free market. Also, you said it's not detached from supply at all, but then proceeded to list reasons detached from supply that affect cost.
