Well,  it might be revolution because beggars now do recognize bitcoin and what it can do,  but in this situation,  I don't think that he is really a homeless person,  considering he even know qr codes.  Being a homeless person means you beg for money for you to have a food to eat,  but this person,  he even have a phone and internet connection,  and this is improbable for a homeless person.  The only way for it to be true is that he do not want to spend money to buy a house,  but I think it is improbable.
