You can be helpful without magic. My parents might disagree, but I've seen it.
Because sometimes you need to survive until you get out of a situation and we have no money. Unless someone here is skilled at hunting, I'm not sure food is something we can strictly just have And if you want to hide your wings, then we need something to go over them. Again. Money. I can handle the stealing parts. I've done it before. Only in situations like this one.
