A dwelling has zero intrinsic value. Ultimately, it only has value if someone is living in it. Having real estate sit empty can only be a temporary affliction.
Supply & demand - it's the law.

Buying real estate to just hold is almost always a losing proposition because of taxes and the time value of money. It is not like a bond, because bonds have guaranteed payouts. Real estate fluctuates in value, quite a lot. It's very easy to lose pots of money in real estate.
Thinking that users will become more desperate is hoping that the government will prevent supply from increasing, or that customers don't simply find other solutions. I suggest looking up what happened when the Hunt Brothers tried to corner the silver market by buying up the supply. Buying up your competition to drive up prices pretty much never works unless the government makes entry of competitors illegal or very hard.
