Well, that is where you lose me... Collecting began because people actually enjoyed the items they collected, whether it was for their beauty, uniqueness, history or whatever. Sometimes collections were built with no forethought; just throw every match book acquired into an old coffee can, for example; no "effort" needed at all. For many, many years, collectors did not collect for value, but for the pleasure the collection brought them, whether it was reading the adventures of their favorite superhero, completing a set of their favorite baseball team trading cards or decorating their house with figurines. In the last three to four decades, collecting has changed from people sharing the same hobby, helping each other find items and trading back and forth; now, collectibles are collected because of their "value" only, by way too many collectors. I still collect because I love what I am collecting, not because it is worth something. Yes, I am just as guilty as most collectors today, in that I will look at items in my collection and think about what they are worth, but I didn't collect it because of that! And I certainly didn't start collecting something because I thought, "Hey, these are going to be difficult to find... should be fun!".
I'm not knocking you or how you collect; there have always been collectors who have collected items because of rarity or value alone, especially in the fields of art, which are mostly one-of-a-kind items anyway. But just because something is produced in the millions, doesn't mean it can't be collectible. If that were the case, then no one would probably have ever collected most coins, stamps or even Hasbro figures in the first place.
