Prop 13 was an effect, not the cause. The cause was and remains a lack of housing supply. Prop 13 was a knee jerk reaction to skyrocketing property values in the 70s caused by (among other things) policy (largely NEPA and CEQA) that was weaponized to make it ever more difficult to build.

Yes, I wouldn't say it's the biggest problem. But it has created a serious block against housing liquidity. Something that protects seniors and those on fixed incomes from losing their homes is good - lots of states have laws like that - but prop 13 is fatally flawed.
