With the established science thing many counterexamples exist, also recent ones. We are now seeing bad outbreaks of preventable disease in undervaccinated communities, because parents increasingly subscribe to unscientific antivax theories. Or corporal punishment, where scientific consensus since 1990s is that it is harmful. The countries which have banned it since did so ahead of change in public opinion. There are times when the government is wrong, but it is by far more right than wrong. Thanks to government intervention we saw childhood mortality drop from the high levels in previous centuries, and letting parents just do their thing would eliminate much of that progress.
