Yeap. In the US, there's been commercial of natural kinds and grocery store PB peanut grinders for decades. Could grind it at home too.

My grandparents used to make their own beef hamburger from sirloin beef and trimmings because the junk in regular hamburger, even from an excellent Italian-American supermarket's butcher counter, was disgusting, to say the least.

Right, but if your only exposure to the stuff has been the super market crap, why would you think to make your own?
