I think we're talking about slightly different things.

What I'm saying is that there's a practical reason why people don't eat raw chicken, to do with the risk to their health.

In my experience people don't make steak tartare at home AT ALL because of the risk of food poisoning, let alone eating raw chicken. We eat cooked meat often because it's easy to store it and prepare it safely. Raising chickens in a more sanitary way is obviously better regardless of whether you're then going to eat the meat raw or not, but I don't think it would be enough on its own to make raw chicken safe enough for people to eat safely, you'd also have to change the supply chain and maybe train chefs preparing the food to keep it safe.

As things stand I'm not completely opposed to eating raw chicken and might try it in a controlled setting but I'd never eat it at home.

Interesting related side note: after the UK left the EU there was a big debate about whether we would accept chlorine washed chicken imported from the US (answer: hell no). Food poisoning from chicken is way more common in the US than here due to different animal welfare and food preparation standards, but that doesn't mean I'm cool with routinely eating raw chicken in the UK.
