Hey, I’m a libertarian, but I hate to spoil your party. Sometimes the experts do know that they are talking about. It could well be that this is simply a sound policy that pervents epidemics whose current temporary absence is one of the miracles of modern life that we all-too-easily take for granted.
One of the traits of CONSERVATIVES is that we not inclined to monkey around with things that we do not fully understand.
The couple who were “shocked” to learn that it is illegal to sell vetables to commercial swine, may have been spared the ordeal of knowing they were responsible for a minor epidemic.
OTOH, this law, like a great many others, may have been an over reaction, using a sledgehammer to kill a gnat, and destroying the kitchen table and the china along with it. I don’t know, and I suspect you don’t either. I do know that needless suffering, disease and anxiety has been caused by ignorance and misinformation about childhool vaccinations, misinformation that was spread either by ignorance, or actual malice.
My view is if the pigs have the cash to pay for it, they can buy anything being sold.
