So you want to remove rent control and exclude hundreds of thousands of people from living in the city just to make it easier for you to find good roommates.
To borrow the words of master spy Sterling Archer: Do you want anarchist protestors? Because that's how you get anarchist protestors.
I'm getting to the point where I should stop feeding the troll, but I'll bite one last time.
No, I would grandfather in everyone in the city with rent control that currently has it and I would work on a legal mechanism that allows the grandfathered in right to rent control to be separated from the underlying property via a mechanism similar to one I've written about before here: https://news.ycombinator.com/item?id=7437658
Rent control messes up all housing markets, reducing the quality and quantity of housing for everyone. We can't undo the mistake that has been made, so the best we can do is find a way to phase it out in a way that allows the market to recover from rent control, but preserve the expectations of those that have come to rely on it. The city needs to increase the supply of housing and the way rent control currently works acts like a lock on a database. The city currently has ~175000 locks on n properties that are essentially undevelopable until you remove all the locks on the property.
I don't want rent control. I, and even most people with rent control, would actually be far better off in a parallel universe where San Francisco had never had rent control. Only those who have been in a property for decades actually benefit. The majority pay far more than they should be for the first couple of years and then in later years end up paying roughly what they would have in the parallel universe where rent control had never happened.
Furthermore, if you lifestyle changes and you want to raise a family, you've fucked yourself out of the market you love because you can't afford anything in the market by the time you decide you might want something different. When someone moves into a rent control place, they effectively check out of the housing market like an ostrich with their head in the sand. Basically, had they been back in the housing market every few years as their housing needs and expectations changed, they would have demanded more housing supply in the city. Rent control permits people to remain blissfully ignorant of the housing situation until one day something happens that causes them to be out of their unit such as an Ellis Act eviction. At that point I think to myself "boo hoo", because if they really wanted to live in a city forever they would have either bought property back when they first moved here or they would have demanded increased housing supply long ago so that they would never find themselves in a housing market they were priced out of. People who argue for rent control are downright selfish, since they basically get the benefits of a scarce good without any of the sacrifice (like saving for a down payment) and actively prevent developments which would reduce the scarcity so that others just like them that arrive later may also enjoy the benefits of living in a city like San Francisco.
