I don't understand why the solution here isn't "ban subletting".
The problem (based in my massive experience of reading one article) seems to be that there are a lot of rent-controlled apartments, but they end users aren't getting the benefit of that low rent controlled price. Instead some private citizens are getting to collect free profit for subletting.
If you make subletting a rent-controlled property illegal, then the people who are living in them are unaffected, and the people who aren't living in them will have to give up their rent-control contract freeing up the property for others.
