That's why you need competition, not Regulation. Resupplying the ISS uses robotically-controlled rockets, so if it fails during launch (likeliest time to fail), no one gets hurt. But it will hurt the reputation of SpaceX, and potentially cause it to go out of business. So if one company falls, you need to have another ready to take it's place.
And the difference between space and the BP oil spill: You can't get a ticket to an oil platform. But people want to go to space. There is an entire future industry, which no doubt is what SpaceX's goal is: to be the first space tourism company.
Now you can imagine what a failure during launch will do to public perception of safety of the company. A failure can kill the space tourism future for SpaceX before it will even start. Safety, I can assure you, is one thing that SpaceX is NOT skimming on. And not because the government is telling it that it can't.
