I don’t really think that a lot of day to day functioning depends on FDA. FDA definitely has a lot to say about a lot of things, and, arguably, without it, some undesirable things would happen more often, but all in all, we would be mostly fine.
If anything, the problem is that when there are no rules, some people (pilots) themselves were reckless and can endanger others. That is something to be solved by criminal courts, though.
