PTFE is a wondrous material, but: PFOA was phased out in US and EU AFAIK, but was for a long time used for making PTFE while contaminating water supplies and drinking water. There were many lawsuits in the USA, see links at end. But note that there are many more potentially dangerous PFAS chemicals that are still used in EU and USA (see links). Also, the PTFE molecule is not a hydrocarbon like most-plastics, it's a fluorocarbon; so you didn't really give a good argument against the idea that people may regret producing a lot of PTFE.
