My 2 cents:
(Sometimes my 2 cents is probably only worth half that... but it's all I've got.)
It's like cheesecake.
If I have no cheesecake, and you give me a slice of cheesecake on my birthday, it's a wonderful gift.
But if I have 10 warehouses full of cheesecake, and you give me a slice of cheesecake on my birthday, I'm just going to think you're touched in the head.
A mere slice of cheesecake would just no longer have any value to me.
