just wait one year OR do some chores, offer to help the neighbors or something like that. It's five bucks, dude, it can't be that hard to obtain, you could even find them in the middle of the road if you look hard enough.
even then, you'd have much more options: an uncle, a grandma, even a friend. But even so, it really doesn't matter, if everyone should care about his problem, every game would be free, because this would be a problem on steam too, so that's a useles argument nonetheless.
