I don't see withholding MLS listings from online listing sites helping brokers in the future. These listings won't get sold because people won't be able to find them online. As a result people will stop listing their homes with brokers. I recently bought my first home, and the negotiating started with "since you aren't using a broker we can take $10k of the listed price". That was the selling broker's opening negotiation, before I even made my initial offer.
