Though what G6 has done and I appreciate her gestures and kindness to this person, sometimes I think you just need to let them be. I know it does seem hard for people to understand why sleep out in the cold, when you can get support from people for a nice warm cosy bed.
If the guy is happy where he is then I would just say leave him be. I'm guessing quite a few people know he is there and when/if the time comes that the guy needs extra help he will do what he needs to do.
This guy, though I'm not comparing him to Brisbane's icon homeless man "Ziggy The Bag Man", sounds like he just wants to be left alone in peace.
Ziggy dislikes the "homeless" word against his name as he does not beg for food, clothes or money and actually admittedly likes his current living arrangements.
I bet a lot of people here would not believe that an homeless man could also become a controversial issue in two consecutive local elections. Well Ziggy has and in doing so has made him an icon of Brisbane, where even tourist come to visit him.
