As a child I was in Cub Scouts and the Boy Scouts.
In Cub Scouts one of our activities to move up from Wolf to Bear was to form a collection of something. There were suggestions of coins or stamps or butterflys.
I collected baseball cards and marbles.
I never liked the idea of forming collections. I never understood the point of it and then I had all this "stuff" I had to maintain and protect. The effort didn't seem worth whatever satisfaction was to be gained.
I did like the baseball cards not for the collection itself but for the value it provided in trading. If a person had a Mickey Mantle or a Willie Mays or a Hank Aaron they were rich and the envy of one's buddies.
I was a humble kid and still am and if I had some highly desired card it made me uneasy and I was very conflicted if I should keep it and brag about it, or trade it for something else which I really didn't care as much about, or maybe even give it to a person who really wanted it to make them happy.
Collections encumber the collector. They require care and maintenance. I got better things to do with my time and energy. .
Now books - that's a whole different story for some other time.
