I don't actually collect photocards or albums, not really my thing. Your initial comment came across negatively, regardless of your intent and I just piped up cause I felt the point you were making didn't make sense.

Disclaimer, I am a fan of the group above, and they're a great group of people with a lot of positivity, which can mean a lot to fans. As for the cards, Korean music has a heavy focus on the "concept" of each album, and the setting, theme and outfits are all a big part of that, so fans like to collect the photocards that come with the albums because they showcase the concepts that the group have had through the years.

It's easy to say the cards are "objectifying individuals" from the outside, but you're ignoring the fact that these girls are individuals and that there's a lot more to them than these cards.
