This applies only to small molecule PFAS, not PFAS polymers, which are about as inert as you can get. You need the small molecules to make the polymers, but there's no reason you need to release them into the environment. Strong regulation (e.g. Chinese style, with lengthy prison sentences or death penalty for CEOs of companies violating them) could enforce strict containment of the reactions and safe disposal of the waste with techniques such as supercritical water oxidation. This would increase the cost, but there's no good substitute for PFAS polymers, so people who really needed them would be willing to pay.
