It depends on demand elasticity. Products with very little demand elasticity like energy or medicine just make everyone miserable and worse off when production is cut, because you can't live without them. Yes you can scrimp and save and stretch your dollar, but at the end of the day you have to pay up no matter the price.
I'm not sure that anyone knows what the demand elasticity for an industrial chemical like PFAS is, but it's obviously not a completely discretionary item.
Energy has a lot of demand elasticity, it just takes a few years for demand to catch up with price changes. See for example how fuel efficiency changed during the oil crisis a few decades ago. Or how building insulation changes with rising energy prices.
