When I wrote about the pre-market arms race, I didn't expect Rob Hahn — one of the most respected voices in the industry — to read it, share it, and write a two-part response laying out how the MLS should fundamentally restructure itself. His framework: "Do Less, MLS." Get the MLS out of marketing, end IDX, and let brokers handle their own listing distribution.This is me reading my honest reaction to that idea — not a counter-proposal or a policy paper, just an everyday broker responding to a big argument from someone I respect. I think Rob is right that the MLS has drifted far beyond its original purpose. But the more I sat with it, the more convinced I became that the whole conversation is focused on the wrong thing. Set marketing aside. The real fight is about data — and who gets to control it.Using Compass's own words from their three-phase marketing strategy, I make the case that private listing networks aren't really a marketing play. They're a data play. And if we let the MLS stop being the single, shared source of truth for the housing market, we don't make it leaner — we make it irrelevant. I close with the part that should keep all of us up at night: what happens to fair and equal access when "only the right ones" get to see a home.Originally published on Realtor Gone Rogue, March 27, 2026.
