I disagree with your own line of thinking. Coddling the renters as should mean creating oversupply of building and housing so that renting prices go down. There is no contradiction in doing that at the same time as improving public service to make the areas desirable.
You're right. The other side of the coin is when owners in places like San Francisco or Brooklyn declare their neighbourhood "historic" and severely restrict building denser housing so they can inflate their property values.
In both cases, the arguments are either disingenuous or misguided.
