There are certain categories of trading cards that can not easily be bought online. I know some people in the actual hobby collection scene for certain trading cards (as opposed to people calling themselves collectors but actually want to just flip for profit). The items these people collect are things such as rare misprints (with population sizes of below 100), physical printsheets (which sometimes have a population size of 1) or promo cards given out for very specific events (such as the creators wedding), again with single- or double digit population sizes. From what I gather the appeal is partly just seeing weird things from the history of a hobby you enjoy. It‘s also a kinda nice way to connect with other people in the collection hobby, since when you run into something wacky you can just call up Jon who collects that exact oddity and bring it to him in exchange for a nice dinner or something.
