> Not to say this isn’t very positive and reducing a problem vastly is great. But a coating that will wear off over years is pretty much a Band-Aid.

Not if you're a company who advertises it as "environmentally safe" and reaps the profits unfortunately. I can see this being used in that way, and this is a perfect advertisement for that. As you said, doesn't really "help" the environment or problem at all aside from making things last a bit longer before they start shedding microplastics. Doesn't mean a company won't use this with manipulative advertising.

I mean, it's been what humanity as a whole has been doing forever. We discover some amazing perfect new solution and invest heavily, until 20 years later we learn it's not as good/safe as we initially thought.
