Great, is that economic research based on thought experiments or reality? I'd love to read it. Let's go back to my example. You build denser housing on top of or next to the condos I mentioned, what happens? The workers move in closer to the city center. The price is low for a short period of time, until more people migrate. Just like when the highway opens up a new lane. The traffic is better for a short period, until more people begin using the highway more. Then you are back to the status quo.

You could argue that you can just keep building up and up until you cross the threshold of demand affecting the price, but without a market incentive to do that, it's wishful thinking at best. "Well the government could fund it" you could say, and indeed it can. But speaking of economic research, everytime the government has done such a thing, it causes widespread economic depression of the local area.
