Earlier quoted context omitted.
This is speculative > and you may just be trading one poison for another one or a worse one. What poison exactly? This almost is whataboutism.
It's not at all speculative. At the very least, getting rid of PFAS will cost money and reduce convenience. Those things are valuable. People will accept some level of risk in order to have comfort and convenience and save money--and to do so is completely rational. That's why people drive, eat red meat, etc.
That's a pretty evil argument, when poisoned people for the most part have no clue they are being poisoned, or even that many are being poisoned due to spread of these chemicals.
"Accept" implies they know the consequences. Those who profit on this, benefit from obscurity.
