> I'm certainly not saying that a "no rent control" situation would be ideal, but I'm wondering if it's just made the rent situation in SF much worse than it would have been otherwise.

I feel that a good proxy for a world without rent stabilization is the condo market. Figure out how much the monthly payment for the low-end and the average condo is, and I suspect that that's where a city full of unstablized rental units would be.
