Rent Control: Rent control causes higher prices for everyone except those who happen to have a rent-controlled apartment, because it discourages improvement of existing properties and discourages building new properties. It also encourages over-buying. Someone may pay $2000/month for a 3 bedroom apartment that has been rent controlled since the 1970s, but only use 1 of the bedrooms. That person could find a 1BR apartment within budget w/o rent control, and someone (maybe 3 room-mates paying $1500 each) could share the 3BR place. Overall this is a more efficient distribution of resources, the benefit of which occurs immediately. I don't really feel sorry for someone getting a huge apartment for way below market price.
Interest Rates: I'm not sure I understand what you mean, since interest rates vary based on unpredictable Fed action and unpredictable market forces all the time. Banks (lenders) hedge against this by buying/selling instruments to even out their Fed risk and by buying insurance to hedge against many of the other risks.
American Auto Industry: What makes you think there would be a chaotic "all at once" situation? That is part of the fearmongering on the part of the firms seeking rents (and the politicians they have bought). Recall how Dubya told everyone that if the US didn't invade Iraq there was an "imminent threat to US national security"? The automakers used that exact strategy to obtain a bailout.
Stability is an interesting concept. It's the essence of "conservatism", wanting to preserve the status quo. Marx warned about this in his manifesto. Anyone who has managed to get a leg up will fight to preserve it at the expense of productive change.
In today's world, this includes the people who thought they were investment geniuses because the value of their home increased 40% the year after they bought it, it includes the overpaid workers who convince themselves that a hard working person immigrating to the US is somehow unamerican, it also includes the politicians who enjoy the huge donations they have been getting from the financial services industry and don't want to see endangered.
So if you put aside the "I want to keep my small advantage at all cost" conservatism, and you do away with the Bush-style fearmongering about imminent threats to "stability", what you find is that the world really isn't all that scary, and often times the meddling that is done to try to prevent "instability" actually does far more harm than good. The Iraq war is a case in point.
Note that "stability in the middle east" is the motto of those who want to go and turn it upside down with bombs and nation building! The same applies to domestic policy.
