True free markets require that both sides of the table have equal access to information, and ultimately are able to negotiate from equal positions of need. People need to be able to walk away from the table too (i.e. lack of coercion on one party or another). Neither is true here, but I’d wager that free market proponents would argue that imbalances are natural, or that people are not being coerced.
Once you start talking about core needs, that becomes a form of coercion in my book. I cannot avoid participating in the housing market, unless I want to deal with all the issues homelessness brings (which includes being much more difficult to hold a job, which effectively excludes me from participation in the market). So I am coerced into participation by the nature of “meet these needs or perish”. So that’s absolutely open to manipulation by those that own housing (i.e. landlords and investment companies that own apartments). The other aspect here is information is not being equally available. And by pooling information together like this, it exacerbates the gap between the two parties. Not to mention this is effectively collusion / price-fixing by algorithm. But since it’s an algorithm doing the collusion, it must be unbiased, right?
Pretty similar to the job market, to be honest. Corporations/employers actively suppress sharing of information in order to have a stronger hand at the negotiation table with employees, on top of the fact that not having a job excludes someone from being able to meet their needs for the vast majority of people.
