Musharbash's argument, however, is dependent on the exercise of oligopoly power (whether he admits that or not, and given that he's long argued that the oligopoly is present...), and there's no evidence of it!

He tries to twist Lambert's words to say he's only saying there's no evidence of builders throttling at a national scale, thereby leaving room for his argument that it's happening in particular markets (https://x.com/musharbash_b/status/1951133245342404888). The only problem? Lambert clearly isn't specifying a national scale when he says "US," because he then continues by providing an explanation for the local weakening seen in some metros.

Musharbash seems smart enough to understand that, which leaves intentional misrepresentation. He's doing damage control, and hoping to wave his hands hard enough that it isn't noticed.
