Neither "regulation" nor "government" are single dimensional quantities that can be compared with a simple "more" or "less".
Having regulatory agencies act in the public interest is probably going to require constant oversight and guidance. It's a hell of a lot harder to have conversations like that when more than half of the political influence in the US is able to dismiss any suggestions with reflexive "more regulation = bad" arguments.
Some regulations decrease competition. Some regulations increase competition. Some regulations provide incentives aligned with the public interest. Some regulations don't. They need to be evaluated on a case by case basis.
Safe regulations are to avoid people dying not to stimulate competition. Without safety regulations, way more people will get sick, injured or die.
And, in this case, it is not about adding more regulation. It is just about making sure that the current one is in place.
Someone though, too much regulation is reducing my profit and 350 people died. Will deregulation bring that people lives back?
