Because it doesn't necessarily result in a safer population. This is software engineering par for the course. Just because you want some software to have some feature doesn't mean that the other requirements and/or reality will cooperate and give you a desirable outcome.
For example, coral snake antivenom. For quite a while the US only had a single coral snake antivenom on the market because it was made by a company that was grandfathered in. The new(ish) FDA rules made developing a new coral snake antivenom not something anyone wanted to do.
So of course the one existing vendor when out of business.
Last I heard (around 2022) people were trying to come up with a new antivenom but thus far have been unsuccessful.
Prescribing that things be safer doesn't force reality to conform and we have examples of this occurring.
