But there are kitchens. And they are as safe as we know how to make them (in principle). But some that don't meet those standards are not allowed to operate.
Same with jets. And buildings. The home construction industry in Miami generally concluded that the codes required on houses there were too strict and expensive, so many did not comply. They could have argued that with the rules there wouldn't be houses.
Then Hugo came, and there were (no longer) houses. Plus, we had an expensive mess to clean up.
So just because something is not allowed to happen because it doesn't meet code doesn't mean that the code failed. Perhaps the code did exactly what it was supposed to do.
There comes a point when all that's left is the question, "how many people can be injured in kitchen accidents per X-thousand fed?" People have become strongly conditioned to insist the answer must be zero. So they pass a laws so that there can only be completely safe kitchens. The law fails because instead of safe kitchens, as intended by lawmakers, there are NO kitchens.
I suppose in a perverted way, you could argue that the law actually was a perfect success. All 0 kitchens are completely safe.
