The market has no telos other than to perform price discovery. I'm not sure where people get the idea that a market will do anything beyond that. Price discovery of housing has no bearing on being able to provide all people with a place to live. It's akin to saying that a market of Fabergé eggs will ensure everyone gets an egg. The problem is simple, there isn't enough housing irrespective of market or planning. Plainly, market-panaceaism is exhausting.
