Earlier quoted context omitted.
Will building more units / appartments/ houses bring the price down? Have other cities seen home prices move toward affordability when more housing has been built? I'm not saying it isn't a good idea, just that the logic seems flawed.
I'm not up on the sources, but a moderately pro-development candidate for Cambridge City Council has often quoted a statistic saying that there are only two ways to bring down house prices: 1. Make the city suck 2. Get the housing vacancy rate to 5.5% And of course he says this to encourage everyone to work toward #2, and the way to do that without displacing anyone is to build new housing. I don't really understand…
It actually fits the "logic" of the model you mentioned.
If you build more housing, the city "sucks less", more people want to live there, so the price goes up. This is especially true with modern development, since it exclusively builds luxury units, which make that part of the city really suck less, and therefore drives prices really high, really fast.

Sure, in the very long run, building new housing lowers prices. But in all short-to-medium timeframes, new housing greatly increases all housing prices in the particular area development occurs, which is why you get so many local residents (even renters) opposed to it.
