There's something to be said for this. All of the great finds over the years are in old cigar boxes or similar containers. And basic card boxes are made of cardboard, just like cards, so no worries about long term chemical reactions of any kind there. While it makes sense that hard plastic slabs or binder pages or any other plastic holder would protect a card better, when it comes to longevity, as in many decades or even a century plus, we don't technically know because they haven't been around that long. So it's all just speculation. In the short term, yeah, hard plastic holders are great because you can drop it and can't bend it or anything. But will that card still be ok in 2122? Who knows. In that amount of time, we don't know if there will be a reaction between the inks and the plastic or perhaps outside forces like UV light or moisture in the air or some other issue that we don't even know about yet. But cards sitting in a cardboard box for that long have been proven to be fine.
