Even if it was sooooo what? people are able to leverage the property and earn more money on it, because it's worth more because somebody is going to pay it. Of course they are going to do that one way or another despite regulation. And they should they are creating more for the economy. If you can't afford to live/work somewhere that's life ? Why on Earth should somebody else subsidize your costs to live there.

That being said I'm sure there are some anti competitive laws/regulations creating problems but the solution is not more bad regulations.
