People aren't just born homeless. He probably had a phone and a bitcoin wallet before ending up on the street. You can find free wifi spots anywhere nowadays. Seems like a normal dude that ended up homeless for whatever reason and is making the best of the resources he has. I've met a few people in that kind of situation and they all had smartphones.
I think they should make money so they can buy a mobile device so they can access the Internet and get more bitcoin like what we do today. it can change their life better and has a good future. but I don't think to ask bitcoin not the only way that they have to do all of their lives. I mean they have to work also to make bitcoin.
