Then, put warning labels and ban it.

If you want people not to accept it so we don't pollute our environment, just prevent the pollution directly. Also, I may not buy things with PFAS but there are millions of situation where PFAS could jeopardize my health (e.g food containers at restaurants, schools, hospitals… neighboring factory producing PFAS, etc).

Maybe (or maybe not - how much attention does the average person pay to California Prop 65 warnings?), but warning labels on consumer products won't do much of anything to curb their use in industry and non-consumer facing products.

We have warning labels and even graphic pictures of diseases on smoking packages but still people choose to smoke.
