I think pokemon collectors shouldn’t worry. I have a baseball card from 1887 that is fine, and was definitely less protected than the average pokemon card. Of course someone who is an expert in materials can weigh in, but in general I would be much more optimistic about any modern trading card. Since pokemon existed there has been third party grading. The baseball card mentioned had to wait almost a century for grading to exist. There are just so many protection options today: sleeves, binders, top loaders, screwdowns, graded slabs, and cases for your graded cards! Not only do more protection & preservation options exist, the average buyer is more condition conscious.
My curiosity is more on what will cleaning options do to cards long term. I’m not suggesting a doom & gloom scenario, its simply a curiosity as its uncharted territory.
