Is there really no alternative in shampoo & disposable coffee cups?

I understand that these chemicals do have some outstanding properties but that doesn't mean unfettered production & use. Any risk assessment of a potential use really should include 100% resource recovery & disposal or recycling. This could have been done years ago but if industry can't self regulate then bans it is.

These chemicals make silent spring look like, um, er, weekend at Bernie's?

Well it's not really a decision between "either not use them at all, or have a proper way to dispose of them"

Yes, there are applications we don't have alternative materials that we can agree are essential like safety products. That being said, we should definitely cut down our use of PFAS for items like floss, cosmetics, etc while continuing to look for alternatives. We use it far too much just for added convenience, but that convenience could be doing a lot of harm.

Kinda like the idea in this article, seems like a good compromise

Depending on their impact, it is often worthwhile to seek alternatives that are less effective or convenient, but also less dangerous. We've had materials in the past which were also deemed "essential", and yet we moved away from them.

A lot of miracle substances tend to be extremely dangerous. There's nothing quite like asbestos when it comes to fire and heat resistance, but we can still make firefighters' clothes, or fireproof buildings, or brakes, even if it means they're heavier or harder to manufacture. R134 and especially R12 make fantastic refrigerants for car AC systems, but we phased those out in favor of substances that are more complex and costly to implement because of the calamitous effect they had on the ozone layer. Carbon tet is an incredible solvent and great at extinguishing fires too. But we don't use that anymore either.

You could be right, maybe there is truly no way around PFOAs, but I'm just calling out a pattern here. And maybe there's no workaround right now that doesn't cause more harm, but with enough research and investment, we can get there in the future.

I agree with you as a realist on the situation. We will never stop manufacturing them, at least for the foreseeable future. But we forget that something like recycling is the last stage of the 3R's to follow. We must first look to reduce consumption. We need to find alternatives where possible, and switch away from these forever chemicals anywhere we can. Next, while "reusing" is not the best term here, but we need to find ways to extend the life of the products that we are forced to use and try to use them up in every way we can. Then lastly we need to be recycling it as best as possible before we send it to an incinerator, or more realistically a developing nation landfill.

Reduce -> Reuse -> Recycle is listed that way for a reason. Everyone always just jumps to the final stage then argue about how bad the recycling is while not even considering ways to reduce or reuse throughout the entire process.

there is no other material known to withstand the temperatures and pressures needed in the production processes?

Production of what, exactly?
