Problem is we have modern science which in same cases has proven that the modern chemicals are less harmful. Remember lead was considered normal for many thousands of years

Modern science can only "prove" that something is not harmful on a timescale of a year or perhaps a decade, not a generation or more. If the precautionary principle had been applied in Roman times, lead would not have been considered safe. Nor asbestos, nor thalidomide, nor microplastics, nor a bunch of synthetic molecules - "proven safe" - that are routinely added to non-organic food in order to improve its yield or its cosmetic aspect or whatever. That was my point.
