That's free market justice right there...
True Government Believers amuse me. They're as deluded as they believe Free Marketers to be. Free Marketers believe the market can fix everything, and True Government Believers believe that laws fix everything. "Without a law people would smear shit on their hands while they make your food!!!"
Yeah. They might. And how does a law stop them?
Most laws don't even attempt to prevent behavior. Instead, they delineate a punishment for breaking of that law that society has established as de facto proper behavior.
Then it becomes...wait for it, FreeMarket zealots...a cost-benefit analysis.
Do you want to not wash your hands, because FreeMarket principles dictate that the consumer must vote with their feet and eat somewhere that doesn't poison them, and risk getting fined?
Or do you take that extra 20 seconds out of your day and wash your hands, thereby not poisoning the consumers of your product.
