There's no benefit to having lead there, some toothpaste didn't have it, so the precautionary principle says, get rid of it. It's totally different from the vaccine where the downside of not having it is clear.
The lead infestation is recent and caused by humans. Lead in the environment was incredibly rare before that, and our lack of exposure during our evolution is why it's so toxic.
This is not true, lead in the environment has been incredibly rare until humans started putting it there. This is actually why it's so toxic, our lack of exposure to it over millions of years of evolution.
There's no safe level of exposure to lead. The reason is that throughout our evolution we've rarely encountered lead or other heavy metals like Mercury. Our bodies are adapted to deal with small amounts of fungus, rat faeces, etc. to the point that small amounts are actually beneficial as the stress triggers our immune system to develop appropriately. This is the difference.
