Once the fluorocarbons are made into PTFE, they no longer pose a threat. Teflon is so biologically inert that it gets used in medical devices implanted into humans. It isn't soluble in water or much of anything else.

The problem is with PFOA and related compounds, which are used to make PTFE and friends.

PFOA specifically is no longer in wide use. Most prominent manufacturers stopped using it as part of the PTFE manufacturing process 10+ years ago. And yes, I agree the science thus far shows that PTFE is basically inert. And to the extent a PTFE coating can separate from a pan, it requires high heat beyond the advertised temperature limits of nonstick pans anyways.

Asbestos is super inert, which made it a very nice material for many applications. However, mechanical interactions of small particles with cellular matter can still cause health issues if I understand correctly. And this is, what the whole fuzz of micro plastics is about, not? Even without biological/chemical reaction, if particle size is small enough, ...

The reasons why asbestos is harmful do not apply to PTFE.

As for micro-plastics, if your claim is that PTFE is no better, but no worse, than, say, polyethylene, well. I suspect you're wrong, and that it's better, but no matter: at that point there's no reason to single it out.
