I think money is useful in and of itself. I mean, doesn't everyone want little peices of paper that feel like cloth, or little pieces of cloth that feel like paper with fancy printing all over them? What could be better than that? And then if you're Canadian you get really colorful stuff, British comes in different sizes, Euros are pretty. Plus it's very useful. You can wipe your counters with it, use it as kindling for fires, metal money is good for weighing things down. THe possibilities are endless!
