The reality of the US Government is that regulations only happen when sufficiently monied interests are diametrically opposed and then some sort of logic sometimes comes out of it.
At least the US model often feels the need to produce something that appears sensible on the surface, although usually with gotchas in subsection 14 part C paragraph 2.
The EPA, NHTSA, FAA, FCC, SEC, etc go through periods of wax and wane with being undermined, then publicly embarrassed, then reconstructed with legitimate people, then undermined, etc. But they exist and ... eventually ... impose regulation.
I have never heard anyone say credibly as a politician to get rid of them, and goddamn are there a lot of corporate forces that want them gone, so as institutions these regulatory agencies have proven themselves.
The FDA however ... I'm pretty down on.
