To be fair, a big part of a functioning society is a government with proper regulations in place so that people are not expected to be experts in literally every field before making a purchase or performing some kind of action. Obviously, calling it "protect[ing] them from themselves," is dismissive and patronizing, but it's pretty much why we need government in the first place.
For example, the EPA recently issued a recall for ground cinnamon from certain specific (dollar store) brands due to unacceptably high levels of lead. Without the career scientists (and yes, bureaucrats) working for that regulatory agency, millions of people would have continued consuming the product and feeding it to their kids (low-income folks too in this case, given the brands) literally indefinitely.
Without the EPA, every person who buys cinnamon is what, expected to use mass spectrometry to determine the exact molecular make-up of every spice (or in the case of the EPA, literally any food or prescription drugs you may ever consume) before using?
If they didn't do their cinnamon research, then they deserved it, and the government should have no involvement? What happens in cases where companies hide dangerous issues in their products to avoid losing profits?
What if there's literally no way for anyone but a scientist, with extensive lab access and at least 4+ years of university to know that there is an issue with a product (or a construction site, or a drug, or water treatment, etc)? They're the only ones who should be able to properly avoid using a product that may kill them and their children? And even then, only when it's a product they're an expert in?
Not saying you're a libertarian, just like pointing out the obvious things that make it so so stupid.
