I'm not saying it necessitates rent control. I'm saying that Prop 13 and rent control both came from the same place, the high inflation 1970s (see the TechCrunch article: http://techcrunch.com/2014/04/14/sf-housing/).
Repealing rent control without repealing Prop 13 would result in a MASSIVE wealth transfer from renters to landlords. I don't think that's fair.
