Food processing laws are there because certain bad things do happen at scale in factories & restaurants that don't happen in home kitchens and when they are personally eating things in the world around them. The laws have to protect the very young, sick and the very old with their compromised immune systems. So there are different standards for different circumstances.

There is also a matter of degree. A commercial food chef needs to wash their hands, a healthy adult person eating prepared meals by other people doesn't need to wear gloves everywhere to be safe.

Also a lot of restaurants and farms are pretty gross places, go work at a fast food place, butcher, meat processing factory and cow farm to see how gross it gets, even with food safety laws & inspections.
