Let me preface this by saying that I'm actually pretty much onboard with a lot of the Libertarian policies that I've heard. Like anything, of course, I think it can be taken too far. So, when you ask for a "very specific example", this is the sort of thing that comes to mind:
- City governments have health inspectors that check local restaurants, and food-product companies to ensure they are using good ingredients, that the equipment is clean, etc. In a libertarian world (at least, certain versions of one) this practice would not exist. Now think what happens when a Monsanto executive realizes that paying the occasional legal suit is cheaper than keeping their packing plants clean and disease-free.
