Your point is valid. It's not clear to me that my claim is true, either. I made it in part because I wondered whether it were true, and I subscribe to the idea that the best way to find out if something is true is not to ask whether it is, but to assert that it is and wait for arguments to the contrary.

But I think it might be partly true, too. As you said, currently "sellers are fine selling at the current prices less commission". When those commissions disappear, sellers who were previously content to get Price - 6%, should still be content to get Price*0.94, since those are the same, and at least in buyer's markets, competing sellers have an incentive to undercut one another in the effort to get their house sold. It seems probable that those would lead to houses moving to a new normal pricing structure 6 percentage points lower than the old normal (less whatever amount the new model is capturing).
