I think those are potentially the two worst examples to pick to argue for deregulation given the huge impacts on people's lives and potential of killing people (healthcare). Banks too though the risks are more from lessons learned from giant banks which you can't become overnight. But consumer protection is a big one, even if deposits are protected, predatory behavior is a big problem and profit center of small banks. I can definitely buy into less regulation for most other businesses or small businesses though.
