I don't see any evidence in that piece of how it "didn't go so well". What I see is sentence after sentence that indicates that there are too few apartments available at reasonable prices. That might be exacerbated by low rents and distorted incentives, but how would it help if more flats were built because prices were high enough to make it attractive?

It might be a demonstration that rent control without appropriate planning controls doesn't work so well. But that's a very different claim.
