I'm about as far left as you can be, as a syndicalist anarchist, and I definitely perceived a bit of what you described. But I'm not super worried about it because he didn't say "the left", but rather a specific lefty position.
But also, the left isn't uniform on housing policy. Some folks want anti trust and limited capital ownership. Some folks want to de commodify housing. Some folks want all housing to be government built and owned. The left is a very diverse place (and the joke is no one hates leftists more than other leftists).
Then why even bother calling it "left" at this point? Just say they're anti-monopoly. Is there really nobody on the right who are also anti-monopoly?
The people the article quoted as "left" like Stoller are really not left, and the whole anti-left felt more like a unnecessary strawman label and definite turn off for me reading it. I would characterize Stoller as an independent anti-monopolist - not really on the right or left spectrum at all politically. Unless the right is now pro-monopoly.
