Blasting off at the speed of light!
I think the feeling here is that given the context of the last year, this product feels kinda gross. Under normal circumstances the worst anyone would likely have to say about it is that it's over priced. Today if feels like catering to the wrong crowd over all.This is completely aside from this product itself, it's just in response to this sentiment I'm seeing around here.
I don't really see any issue with wanting to collect sealed products as well as protecting them. I feel like there's this weird misconception around these comments that this exclusively for "resale" purposes. Some people just want to collect sealed Pokémon things. Whether it be packs, ETBs, booster boxes, etc. I have friends who are like this, collecting them just for the sake of collecting them. Even I collect a small handful of sealed products, namely with Empoleon on them, because it is a unique item with my favorite Pokémon on it, that is beyond just cards.
I also think it's perfectly fine wanting to preserve these types of things, given that they're a part of Pokémon history in a way- especially if they're scarce, such as things like older booster boxes. If I had a sealed Skyridge box, for instance, I wouldn't open it, as tempting as it would be. The cards in the box are much more common than the box itself.
These sealed products can have a collectible appeal to people, and thus, they can be considered collectibles. And if something is collectible, isn't it only sensible to want to protect the thing you're collecting? Especially if it's something like a booster box which can be easily damaged? There are tens of thousands of people out there who keep things sealed just to keep them as such, to keep that specific product as its own collectible. Wanting to protect a box isn't solely for value appreciation... And even if it was, It's just like keeping your cards in some sleeves and toploaders. It's so they stay in good shape. And much like @Citrus said, it helps with displaying a box instead of just leaving it on a shelf or whatever.
I don't see what makes this encouraging "disgusting" behavior.
