That's a grossly misleading argument. Chemicals exist in groups. If sufficiently safety information isn't available about a chemical, the safety of its group can be relied upon, and this is sufficient for initial regulation. In contrast, grandfathering is erroneous, dangerous, and heinous. Additionally, safety often is a function of chain length as well. Besides, we have AI and quantum chemistry too to formulate great estimates until perfect information becomes available. I have heard enough Ayn Rand style nonsense to know that it's nonsense. Her cult members will sell their wife and mother for money for a price, and they cannot be entrusted with environmental safety.
